Currently, the dose detection method is the "Standard Method for Measuring Gamma Ray Water Absorbed Dose Using a Silver Dichromate Dosimeter" JJG 1028-91, which was implemented in 1992. This method was published and implemented in the early 1990s and has been in use for more than 30 years.

[0003] However, current methods for detecting radiation dose have high requirements for personnel operation and environment, and the detection operation is relatively complex, resulting in long measurement times and low efficiency in generating radiation dose results. To address this, to reduce testing time and improve efficiency, current methods typically determine the radiation dose by analyzing the change in absorbance of the dosimeter before and after irradiation and then using a conversion factor. However, this method of directly detecting the overall absorbance of the test light is often susceptible to interference between light rays with different index information, leading to increased dose measurement errors and reduced data value. Summary of the Invention

[0004] The purpose of this invention is to provide an irradiation dose detection method, device, electronic device, and readable storage medium to solve the problem in the prior art where mutual interference between light rays under different index information leads to increased dose measurement error and reduced data value.

[0005] To achieve the above objectives, the present invention provides an irradiation dose detection method, which is applied to an irradiation dose detection device, the irradiation dose detection device comprising: a light source device, a detection cell, a detector, and a data processor;

[0006] The irradiation dose detection method includes:

The initial light passes through the detection cell and the dosimeter in the detection cell to form a measurement light.

[0014] If the light source device determines that the fluctuation amplitude index, fluctuation frequency index, and stability index all meet the index standards corresponding to the fluctuation amplitude information and the fluctuation frequency information, then the light to be measured is determined as the initial light.

[0015] If the light source device determines that one or more of the fluctuation amplitude index, fluctuation frequency index, and stability index do not meet the index standard, then the light source device shall be subjected to one or more adjustment operations of temperature adjustment, power adjustment, and power compensation adjustment to obtain a new light to be measured.

[0019] The detector performs spectral splitting on the first ray based on the index information to obtain multiple second rays;

[0020] The detector assigns each of the second rays to a corresponding detection unit.

[0021] In the above scheme, each detection unit detects the received measurement light to obtain the unit absorbance of each detection unit, including:

[0022] The first detection unit acquires a measurement function; wherein the measurement function is as follows:

[0023] A = tlg(I0 / I); where I0 is the light intensity of the initial light, I is the light intensity of the measured light, and t is the absorbance adjustment coefficient under the index information corresponding to the first detection unit; the first detection unit is one of at least one detection unit;

[0025] If the first detection unit determines that there is an abnormal absorbance among the N single absorbance values, then deletes the abnormal absorbance value from the N single absorbance values.

[0026] If the first detection unit determines that there is no abnormal absorbance among the M single absorbance values, then the average of the M single absorbance values ​​is taken as the unit absorbance of the first detection unit; where M is a natural number less than or equal to N and greater than or equal to 1.

[0027] In the above scheme, the data processor obtains the dosimeter absorbance based on the absorbance of at least one of the units, including:

[0030] In the above scheme, the data processor obtains the irradiation dose result based on the dosimeter absorbance of the first measuring light and the dosimeter absorbance of the second measuring light, including:

[0031] The data processor acquires a difference function; the difference function is as follows:

[0032] S1 = m1 × A1 + n1;

[0033] S2 = m2 × A2 + n2;

[0034] ΔA = S1 – S2;

[0035] Where A1 is the dosimeter absorbance of the first measuring light and A2 is the dosimeter absorbance of the second measuring light;

[0036] m1 is the first adjustment coefficient corresponding to the temperature and humidity inside the radiation dose detection device when the first measuring light is formed, and m2 is the second adjustment coefficient corresponding to the temperature and humidity inside the radiation dose detection device when the second measuring light is formed.

[0038] S1 is the dosimeter absorbance of the first measuring light after adjustment for temperature and humidity factors, and S2 is the dosimeter absorbance of the first measuring light after adjustment for temperature and humidity factors.

[0039] ΔA is the irradiation dose result;

[0040] When the first measuring light is formed in the irradiation dose detection device, the sensing device of the data processor collects the first temperature value and the first humidity value in the irradiation dose detection device, and determines the first adjustment coefficient and the first bias value from a preset temperature and humidity mapping table based on the first temperature value and the first humidity value.

[0044] To achieve the above objectives, the present invention also provides an irradiation dose detection device, comprising: a light source device, a detection cell, a detector, and a data processor;

[0045] The light source device is used to receive fluctuation amplitude information and fluctuation frequency information, and emit initial light into the detection cell according to the fluctuation amplitude information and fluctuation frequency information.

[0047] The data processor is used to obtain the dosimeter absorbance based on the absorbance of at least one of the units;

[0048] The data processor is further configured to obtain an irradiation dose result based on the dosimeter absorbance of the first measuring light and the dosimeter absorbance of the second measuring light; wherein, the first measuring light is the measuring light formed when the initial light passes through the dosimeter before irradiation; the second measuring light is the measuring light formed when the initial light passes through the dosimeter after irradiation; the irradiation dose result characterizes the difference in absorbance of the dosimeter before and after irradiation.

[0049] To achieve the above objectives, the present invention also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor.

The irradiation dose detection method, apparatus, electronic device, and readable storage medium provided by the present invention distribute the measurement light to multiple detection units, achieving absorbance detection under multi-dimensional index information. This eliminates interference between light sources with different index information, improves absorbance measurement accuracy, reduces irradiation dose measurement error, and enhances data value. By integrating the detection results of at least one unit through a data processor, absorbance calculation is further optimized, avoiding interference from outliers in a single unit.

[0059] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0060] As early as 1980, the Joint FAO / WHO Expert Committee on Food Safety and Sanitary Safety of Irradiated Food, composed of the Food and Agriculture Organization of the United Nations, the World Health Organization, and the International Atomic Energy Agency, set the upper limit of food irradiation dose at 10 kGy. The determination of this standard dose greatly promoted the commercialization of food irradiation technology. Any food irradiated with a dose below 10 kGy will not cause any toxicological hazards. Furthermore, numerous hygiene and safety experiments in this study have proven that irradiated food is safe for consumption and will not cause nutritional or microbiological problems. Therefore, controlling the irradiation dose is a crucial technical parameter for ensuring the safety of irradiated food and agricultural products. my country's general standard for food irradiation, the "National Food Safety Standard for Hygienic Specifications of Food Irradiation Processing" (GB18524-2016), has detailed requirements regarding food irradiation dose, such as clear testing requirements for irradiation process dose, routine dose, daily dose, and product dose. Irradiation dose testing is directly related to the quality and safety of irradiated food and agricultural products.

[0061] Dosimetry in irradiation processing is the most critical step in controlling irradiation quality. Currently, the standard method for dosimetry is the "Standard Method for Measuring Gamma-Ray Water Absorbed Dose Using a Silver Dichromate Dosimeter" (JJG 1028-91), implemented in 1992. This method was published and implemented in the early 1990s and has been in use for over 30 years. The preparation of the dosimeter has high requirements for personnel operation and environment, the detection operation is relatively complex, and the requirements for detection personnel are high. Furthermore, the operation is cumbersome when using different dosimeters for alternating detection, which leads to increased labor costs. In addition, with the continuous improvement of food safety management requirements, irradiation, as an auxiliary process in food processing, requires improved food safety traceability management.

[0062] The technical principle underlying this application is based on the change in absorbance of a potassium dichromate (silver) dosimeter before and after irradiation. By using a dose response conversion factor K, the dosimeter irradiation dose can be obtained. Specifically, the absorbance of the dosimeter before and after irradiation (radioactive cobalt-60, high-energy electron acceleration, X-rays) is detected, and the absorbance value is collected. After mathematical processing by a data processor of a dedicated detection device, the irradiation dose can be obtained, achieving the purpose of rapid determination of irradiation dose. Compared with other methods, the overall detection time can be shortened by more than 90%. There are no reports on this invention method in irradiation dose detection.

[0063] Example 1:

[0064] Please see Figure 1 and Figure 2 This application provides an irradiation dose detection method, which is applied to an irradiation dose detection device, the irradiation dose detection device including: a light source device 1, a detection cell 2, a detector 3 and a data processor 5;

[0065] The irradiation dose detection method includes:

[0066] S101: The light source device 1 receives fluctuation amplitude information and fluctuation frequency information, and emits initial light to the detection cell 2 according to the fluctuation amplitude information and fluctuation frequency information. The initial light passes through the detection cell 2 and the dosimeter in the detection cell 2 to form a measurement light.

[0067] S102: The detector 3 receives the measurement light and distributes the measurement light to each detection unit 4; wherein the detector 3 has at least one detection unit 4;

[0068] S103: Each of the detection units 4 detects the measurement light it receives and obtains the unit absorbance of each detection unit 4; the unit absorbance reflects the absorbance of the dosimeter under different index information.

[0069] S104: The data processor 5 obtains the dosimeter absorbance based on the absorbance of at least one of the units;

[0070] S105: The data processor 5 obtains the irradiation dose result based on the dosimeter absorbance of the first measuring light and the dosimeter absorbance of the second measuring light; wherein, the first measuring light is the measuring light formed when the initial light passes through the dosimeter before irradiation; the second measuring light is the measuring light formed when the initial light passes through the dosimeter after irradiation; the irradiation dose result characterizes the difference in absorbance of the dosimeter before and after irradiation.

[0071] In this example, by distributing the measurement light rays to multiple detection units 4, absorbance detection under multi-dimensional index information is achieved. This eliminates interference between light rays with different index information, improves absorbance measurement accuracy, reduces irradiation dose measurement error, and enhances data value. The data processor 5 integrates the detection results of at least one unit to further optimize absorbance calculation and avoid interference from outliers in a single unit. Therefore, by using multiple detection units 4 to collaboratively measure and compare absorbance before and after states, the low measurement accuracy problem in traditional methods is solved, achieving highly reliable and accurate irradiation dose calculation, suitable for scenarios with strict requirements for dose measurement accuracy.

[0072] In a preferred embodiment, the light source device 1 receives fluctuation amplitude information and fluctuation frequency information, and emits initial light to the detection cell 2 according to the fluctuation amplitude information and fluctuation frequency information, including:

[0073] S11: The light source device 1 generates the light to be measured based on the fluctuation amplitude information and the fluctuation frequency information, and the light source device 1 detects the fluctuation amplitude index, fluctuation frequency index and stability index of the light to be measured;

[0074] S12: If the light source device 1 determines that the fluctuation amplitude index, fluctuation frequency index, and stability index all meet the index standards corresponding to the fluctuation amplitude information and the fluctuation frequency information, then the light to be measured is determined as the initial light.

[0075] S13: If the light source device 1 determines that one or more of the fluctuation amplitude index, fluctuation frequency index, and stability index do not meet the index standard, then the light source device 1 shall be subjected to one or more adjustment operations of temperature adjustment, power adjustment, and power compensation adjustment to obtain a new light to be measured.

[0076] In this example, in applications such as light measurement, the quality of the initial light is crucial for subsequent measurement and analysis. By detecting the fluctuation amplitude, fluctuation frequency, and stability of the light to be measured generated by the light source device 1, and judging according to preset index standards, the light to be measured is determined as the initial light only when all these indicators meet the standards. This ensures that the initial light has stable and reliable quality, laying the foundation for subsequent accurate measurement or processing.

[0077] When one or more of the fluctuation amplitude, fluctuation frequency, and stability indicators are detected to be non-compliant with preset standards, one or more operations are performed on the light source device 1, including temperature adjustment, power adjustment, and power compensation adjustment. This adjustment mechanism can promptly correct problems in the performance of the light source device 1, helping to improve its performance stability and enabling it to continuously generate initial light that meets requirements, reducing measurement errors or system failures caused by light source instability.

[0078] Further, the light source device 1 generates the light to be measured based on the fluctuation amplitude information and the fluctuation frequency information. The light source device 1 detects the fluctuation amplitude index, fluctuation frequency index, and stability index of the light to be measured, including:

[0079] S111: The light source device 1 detects the light intensity amplitude value, the relative rate of change of light intensity, and the root mean square fluctuation value of light intensity of the light to be measured, and summarizes them to obtain the fluctuation amplitude index; wherein, the light intensity amplitude value is the difference between the maximum light intensity value and the minimum light intensity value;

[0080] S112: The light source device 1 detects the main fluctuation frequency, fluctuation frequency distribution range, and high-frequency noise ratio of the light to be measured, and summarizes them to obtain the fluctuation frequency index.

[0081] S113: The light source device 1 detects the long-term average light intensity drift, light intensity standard deviation, and light intensity stabilization time ratio of the light to be measured, and summarizes them to obtain the stability index.

[0082] In this example, by conducting detailed testing on the light source device 1 from three dimensions—fluctuation amplitude, fluctuation frequency, and stability—the quality of the light generated by the light source device 1 can be evaluated more comprehensively and accurately. Traditional methods may only focus on a single indicator, while this approach comprehensively considers multiple key indicators, avoiding overlooking other potential problems due to the achievement of a single indicator, and providing a more reliable basis for subsequently determining whether to use the light to be measured as the initial light.

[0083] The light to be measured is determined as the initial light only when the fluctuation amplitude, fluctuation frequency and stability index of the light source device 1 meet the preset standards. This ensures that high-quality and stable light is used in subsequent applications, thereby improving the reliability and performance of the entire system.

[0084] Further, one or more adjustment operations are performed on the light source device 1, including temperature adjustment, power adjustment, and power compensation adjustment, to obtain a new light to be measured, including:

[0085] S131: If the light source device 1 determines that the fluctuation amplitude index does not meet the index standard, the power of the drive module of the light source device 1 is adjusted to obtain a new light to be tested.

[0086] S132: If the light source device 1 determines that the fluctuation frequency index does not meet the index standard, the temperature control module of the light source device 1 is adjusted to obtain a new light to be measured.

[0087] S133: If the light source device 1 determines that the stability index does not meet the index standard, then the light source device 1 is adjusted by feedforward compensation based on historical fluctuation data to obtain a new light to be measured.

[0088] In this example, when the fluctuation range indicator fails to meet the standard, the power of the drive module is adjusted. This is because the power of the drive module directly affects the luminous intensity of the light source; adjusting the power changes the light intensity, thereby adjusting the fluctuation range of the light intensity to meet the standard.

[0089] When the fluctuation frequency does not meet the requirements, the temperature control module is adjusted. Temperature has a significant impact on the light emission characteristics of the light source. The electronic transitions and atomic vibrations of the light source change at different temperatures, thus affecting the fluctuation frequency of the light. The fluctuation frequency can be optimized by adjusting the temperature.

[0090] For situations where stability indicators fail to meet standards, multiple adjustment methods are employed. Temperature adjustment can improve the performance instability of light source device 1 caused by temperature changes; feedforward compensation adjustment based on historical fluctuation data can compensate for potential fluctuations in advance based on past data, enhancing system stability; closed-loop power correction adjustment based on real-time detection results can fine-tune the power in real time according to the current light conditions, ensuring stable light quality.

[0091] This situation-specific and targeted adjustment approach avoids blind adjustments, enabling rapid identification of the root cause of the problem and the implementation of effective measures, thus improving adjustment efficiency. The combined use of multiple adjustment methods optimizes the light source device 1 from different perspectives, enhancing the adjustment effect.

[0092] Optionally, if it is determined that the fluctuation amplitude index does not meet the index standard, then the power of the drive module of the light source device 1 is adjusted, including:

[0093] If the light source device 1 determines that the fluctuation amplitude index is less than the lower limit of the fluctuation amplitude range in the index standard, then according to the preset duty cycle adjustment step, the current duty cycle of the drive module of the light source device 1 is increased.

[0094] When the Pth adjustment causes the fluctuation amplitude index of the initial light emitted by the light source device 1 to exceed the lower limit of the fluctuation amplitude range, and the Qth adjustment causes the fluctuation amplitude index of the initial light emitted by the light source device 1 to exceed the upper limit of the fluctuation amplitude range, the light source device 1 calculates the difference between Q and P to obtain the adjustment difference.

[0095] If the light source device 1 determines that the number of times the adjustment difference is greater than or equal to two, then the average of the current duty cycle of the driving module at the Pth adjustment and the current duty cycle of the driving module at the Q-1th adjustment is taken as the final adjustment current duty cycle, so that the driving module drives the light source device 1 according to the final adjustment current duty cycle to generate a new light to be measured.

[0096] If the light source device 1 determines that the number of times the adjustment difference is increased is one, it reduces the adjustment amplitude and increases the current duty cycle of the drive module of the light source device 1 according to the reduced adjustment amplitude.

[0097] If the light source device 1 determines that the fluctuation amplitude index is greater than the upper limit of the fluctuation amplitude range in the index standard, then it reduces the current duty cycle of the drive module of the light source device 1 according to the preset reduction duty cycle step.

[0098] When the Xth adjustment causes the fluctuation amplitude index of the initial light emitted by the light source device 1 to be lower than the upper limit of the fluctuation amplitude range, and the Yth adjustment causes the fluctuation amplitude index of the initial light emitted by the light source device 1 to be lower than the lower limit of the fluctuation amplitude range, the light source device 1 calculates the difference between Y and X to obtain the adjustment difference.

[0099] If the light source device 1 determines that the number of times the adjustment difference is greater than or equal to two, then the average of the current duty cycle of the driving module at the Xth adjustment and the current duty cycle of the driving module at the (Y-1)th adjustment is taken as the final adjustment current duty cycle, so that the driving module drives the light source device 1 according to the final adjustment current duty cycle to generate a new light to be measured.

[0100] If the light source device 1 determines that the number of times the adjustment difference is reduced is one, it reduces the adjustment magnitude and adjusts the current duty cycle of the drive module of the light source device 1 according to the reduced adjustment magnitude.

[0101] In this way, the fluctuation amplitude index of the test light corresponding to the final upward adjustment of the current duty cycle and the final downward adjustment of the current duty cycle is brought closer to the midpoint of the fluctuation amplitude range, making the quality of the generated initial light more stable.

[0102] The fluctuation range includes: the light intensity amplitude range, the relative change range of light intensity, and the root mean square fluctuation range of light intensity.

[0103] The fluctuation amplitude index being less than the lower limit of the fluctuation amplitude range refers to one or more of the following: the light intensity amplitude value being less than the lower limit of the light intensity amplitude range, the relative rate of change of light intensity being less than the lower limit of the relative rate of change of light intensity, and the root mean square fluctuation value of light intensity being less than the lower limit of the root mean square fluctuation range of light intensity.

[0104] The fluctuation amplitude index being greater than the upper limit of the fluctuation amplitude range refers to one or more of the following: the light intensity amplitude value being greater than the upper limit of the light intensity amplitude range; the relative rate of change of light intensity being greater than the upper limit of the relative rate of change of light intensity; and the root mean square fluctuation value of light intensity being greater than the upper limit of the root mean square fluctuation range of light intensity.

[0105] P, Q, X, and Y mentioned above are natural numbers greater than or equal to 1.

[0106] Optionally, if it is determined that the fluctuation frequency index does not meet the index standard, the temperature control module of the light source device 1 is adjusted to obtain a new light to be measured, including:

[0107] If the light source device 1 determines that the fluctuation frequency index is less than the lower limit of the fluctuation frequency range in the index standard, then it adjusts the temperature of the temperature control module R times according to the preset temperature adjustment step, to obtain R adjusted temperature values ​​and R temperature-adjusted light rays.

[0108] If the light source device 1 determines that S out of R temperature-adjustable rays are within the fluctuation frequency range, and the value of S is greater than or equal to two, then the average of the S adjustment temperature values ​​corresponding to the S temperature-adjustable rays is taken as the final adjustment temperature value. The temperature control module controls the temperature of the light source device 1 according to the final adjustment temperature value, so that the light source device 1 generates a new light to be measured corresponding to the final adjustment temperature value.

[0109] If the light source device 1 determines that the fluctuation frequency index is greater than the upper limit of the fluctuation frequency range in the index standard, then it adjusts the temperature of the temperature control module T times according to the preset temperature reduction step, to obtain T adjusted temperature values ​​and T temperature-reduced light.

[0110] If the light source device 1 determines that U of the T temperature-adjusted light rays are within the fluctuation frequency range, and the value of U is greater than or equal to two, then the average of the U temperature adjustment values ​​corresponding to the U temperature-adjusted light rays is taken as the final temperature reduction value. The temperature control module controls the temperature of the light source device 1 according to the final temperature reduction value, so that the light source device 1 generates a new light ray to be measured corresponding to the final temperature reduction value.

[0111] This method ensures that the light rays corresponding to the final upward and downward temperature values ​​can remain stable within the fluctuation frequency range for an extended period.

[0112] The main fluctuation frequency, fluctuation frequency distribution range, and high-frequency noise ratio of the light source device 1

[0113] The fluctuation frequency range includes: the main fluctuation frequency range, the fluctuation frequency distribution range, and the high-frequency noise proportion range;

[0114] The fluctuation frequency index being less than the lower limit of the fluctuation frequency range in the index standard includes one or more of the following: the main fluctuation frequency being less than the lower limit of the main fluctuation frequency range, the fluctuation frequency distribution range being less than the lower limit of the fluctuation frequency distribution range segment, and the high-frequency noise proportion being less than the lower limit of the high-frequency noise proportion range.

[0115] The fluctuation frequency index being less than the upper limit of the fluctuation frequency range in the index standard includes one or more of the following: the main fluctuation frequency being less than the upper limit of the main fluctuation frequency range, the fluctuation frequency distribution range being less than the upper limit of the fluctuation frequency distribution range segment, and the high-frequency noise proportion being less than the upper limit of the high-frequency noise proportion range.

[0116] R, S, T, and U mentioned above are natural numbers greater than or equal to 1.

[0117] Optionally, if it is determined that the stability index does not meet the index standard, then the light source device 1 is adjusted by feedforward compensation based on historical fluctuation data to obtain a new light to be measured, including:

[0118] If the light source device 1 determines that the stability index does not meet the stability standard of the index standard, it calls a preset index adjustment mapping table to perform feedforward compensation adjustment on the light source parameters of the light source device 1 to obtain a new light to be measured. The index adjustment mapping table is obtained by training a machine learning model on historical fluctuation data, representing the mapping relationship between stability indices and light source parameter adjustment amounts. The stability indices include: average light intensity drift, light intensity standard deviation, and light intensity stabilization time ratio. The stability standard includes: the range of average light intensity drift, the range of light intensity standard deviation, and the range of light intensity stabilization time ratio. The historical fluctuation data records the process of adjusting the light source parameters of the light source device 1 when one or more of the average light intensity drift, light intensity standard deviation, and light intensity stabilization time ratio are higher or lower than the stability standard, so that the stability index of the light to be measured generated by the light source device 1 meets the stability standard. The light source parameters include the duty cycle of the driving module and the temperature value of the temperature control module.

[0119] Therefore, by adjusting the feedforward compensation of the light source parameters, the duty cycle and / or temperature value can be adjusted in advance, enabling the light source device 1 to directly generate test light whose stability index meets the stability standard.

[0120] In a preferred embodiment, the indicator information is one or more of wavelength indicators, phase indicators, and polarization indicators.

[0121] First, if the test light is broadband light (such as white light), the molar absorptivity ε varies for different wavelengths. Directly detected absorbance A is a weighted average of the absorbance at each wavelength, failing to reflect the absorption characteristics of a specific wavelength band. The dosimeter and / or detection cell 2 exhibits strong absorption at 600nm (high ε600) and weak absorption at 800nm ​​(low ε800). If the intensity ratio of these two wavelengths in the test light is 1:1, direct detection will underestimate the contribution of 600nm light, leading to overall absorbance measurement deviation. Therefore, by setting wavelength parameters, the limitations caused by directly detecting the absorbance of the test light are resolved. Simultaneously, by using a grating, prism, or interferometer to decompose broadband light into monochromatic light (or narrow-spectrum light), and independently measuring the absorbance A(λ) for each wavelength, inter-wavelength interference is eliminated, accurately obtaining the absorption characteristics of each wavelength band and improving detection sensitivity. For example, when detecting hemoglobin and bilirubin in blood, spectrophotometry can simultaneously utilize the characteristic absorption of hemoglobin at 540nm and bilirubin at 450nm, avoiding cross-interference caused by wavelength mixing in direct detection.

[0122] Secondly, if the dosimeter and / or detection cell 2 absorbs light differently for different polarization directions (e.g., anisotropic crystals, liquid crystal materials), direct detection using natural light (unpolarized light) or uncalibrated polarized light will result in an average absorbance for each polarization component, failing to reflect the true polarization dependence. For example, if the dosimeter and / or detection cell 2 absorbs vertically polarized light 20% more than horizontally polarized light, and the test light is natural light (vertical to horizontal polarization intensity ratio is 1:1), direct detection will underestimate the actual absorbance under vertically polarized light, leading to dose or concentration measurement errors. Therefore, by setting polarization indices, the light is decomposed into vertical (s-polarization) and horizontal (p-polarization) components, and the absorbance As and Ap are measured separately, or the polarization characteristics are comprehensively described using the Mueller matrix. Accurate quantification of polarization-dependent absorption is applicable to anisotropic dosimeters and / or detection cell 2, improving the signal-to-noise ratio and anti-interference capability.

[0123] Finally, if the test light contains multiple phase-correlated beams (such as coherent light or light that has been scattered / reflected), direct detection will cause interference between beams of different phases, resulting in periodic fluctuations in the transmitted light intensity I (such as interference fringes) instead of monotonic absorption attenuation. In this case, the directly measured absorbance A = −log(I / I0) will deviate from the true value due to the interference effect. For example, when detecting thin film thickness, if coherent light (such as a laser) is used, direct detection will cause the absorbance to change periodically with the film thickness due to interference between the reflected light from the upper and lower surfaces of the film (equal thickness interference or equal inclination interference), failing to accurately reflect the true absorption characteristics. By separating light of different phases, the periodic modulation of absorbance by the interference effect can be avoided, allowing direct acquisition of the true absorption signal and improving detection sensitivity.

[0124] In a preferred embodiment, the detector 3 receives the measurement light and distributes the measurement light to each detection unit 4, including:

[0125] S21: When the measuring light reaches the receiving area of ​​the control detector 3, the detector 3 introduces the measuring light into the detector 3 through optical coupling and performs preliminary processing on the measuring light to obtain the first light.

[0126] S22: The detector 3 performs spectral splitting on the first light beam according to the index information to obtain multiple second light beams;

[0127] S23: The detector 3 assigns each of the second rays to a corresponding detection unit 4.

[0128] In this example, optical coupling is a technique for efficiently transmitting light from one optical system to another. It utilizes the physical properties of light, such as refraction and reflection, to maximize the entry of the measurement light into detector 3, minimizing light loss and scattering. Ensuring the measurement light can smoothly enter detector 3 provides sufficient light intensity for subsequent processing and analysis, preventing inaccurate detection results due to insufficient light intake.

[0129] The indicator information provides clear objectives and basis for spectroscopic processing, ensuring that the second ray after spectroscopic division can meet the needs of subsequent detection and analysis, and selectively acquire information on different characteristics of the measurement ray. The first ray is decomposed into multiple second rays with different characteristics, so that these second rays can be detected and analyzed separately to obtain detailed information on different components of the measurement ray.

[0130] Each of the second rays is assigned to a corresponding detection unit 4, ensuring that each second ray can be accurately detected by the specially designed detection unit 4, thereby improving the accuracy and sensitivity of the detection. This achieves a one-to-one correspondence between the second rays and the detection units 4, enabling each detection unit 4 to independently detect and analyze a specific second ray, thereby obtaining detailed data on different characteristics of the measured rays and providing an accurate basis for subsequent data processing and result analysis.

[0131] Furthermore, the detector 3 introduces the measurement light into itself via optical coupling, and controls the circuitry and sensors inside the detector 3 to perform preliminary processing on the measurement light to obtain a first light beam, including:

[0132] S211: The detector 3 introduces the measurement light into the detector 3 through any one of the following methods: free space optical coupling, fiber optic coupling, and waveguide coupling;

[0133] S212: The detector 3 performs light intensity reference correction, dark current compensation and noise suppression processing on the measured light to obtain the first light.

[0134] Furthermore, the detector 3 performs spectral splitting on the first ray based on the index information to obtain multiple second rays, including:

[0135] S221: The detector 3 splits the first light beam through a preset dispersive element to obtain multiple second light beams;

[0136] S222: The detector 3 splits the first light beam through a preset interference element to obtain multiple second light beams;

[0137] S223: The detector 3 splits the first light beam through a preset polarization element to obtain multiple second light beams.

[0138] S224: The detector 3 splits the first light beam using a preset dispersive element and an interference element to obtain multiple second light beams;

[0139] S225: The detector 3 splits the first light beam using a preset interference element and polarization element to obtain multiple second light beams;

[0140] S226: The detector 3 splits the first light beam using a preset dispersive element and a polarizing element to obtain multiple second light beams;

[0141] S227: The detector 3 splits the first light beam by using a preset dispersive element, interference element and polarization element to obtain multiple second light beams.

[0142] The dispersive element is configured with multiple wavelength ranges, each wavelength range serving as a wavelength index to split the first ray and obtain a second ray.

[0143] The interference element is equipped with multiple phase ranges, each of which serves as a phase index to split the first ray and obtain a second ray.

[0144] The polarization element has multiple polarization ranges, each of which serves as a polarization index to split the first ray and obtain a second ray.

[0145] In this example, free-space optical coupling refers to the transmission and coupling of optical signals from one optical device to another by changing the direction of light propagation, focusing, or collimating it through optical elements (such as lenses, mirrors, etc.) in free space (i.e., an unconstrained medium, usually air). Its core principle is based on the laws of rectilinear propagation, reflection, and refraction of light.

[0146] Fiber optic coupling is a coupling method that uses optical fibers to transmit optical signals. An optical fiber is an optical waveguide composed of a core, cladding, and coating. Its working principle is based on the phenomenon of total internal reflection. When light propagates in the core, because the refractive index of the core is greater than that of the cladding, total internal reflection occurs at the interface between the core and cladding, thus confining the light to the core. Optical signal transmission is achieved by coupling light from a light source into the optical fiber and then coupling it from the other end of the fiber to a light receiving device.

[0147] Waveguide coupling refers to the propagation of light within a waveguide structure, enabling the transmission and interaction of optical signals between different waveguides or between a waveguide and other optical devices through specific coupling elements or structures. A waveguide is an optical structure that can confine the propagation path of light, and its working principle is also based on the phenomenon of total internal reflection.

[0148] A dispersive element is a component in a spectrometer that disperses composite light into spectral lines or monochromatic light, thus performing a spectroscopic function. Its working principle is based on the phenomenon of light dispersion, that is, light of different wavelengths is separated when it propagates in a medium due to differences in refractive index.

[0149] Interference elements are optical devices made using the principle of light interference to generate, control, or analyze light interference phenomena. When two or more coherent light waves superimpose at a point in space, the resulting intensity distribution due to the addition of their amplitudes is called interference. By designing specific optical structures, interference elements can cause light waves to interfere under specific conditions, thereby enabling the modulation, filtering, or analysis of optical signals.

[0150] A polarizing element is a device that obtains plane-polarized light from natural light. It is defined as a device that converts unpolarized light into linearly polarized light by selectively transmitting or reflecting light waves with specific vibration directions. The working principle of a polarizing element is based on the transverse wave properties of light and crystal optical effects, utilizing physical mechanisms such as the anisotropy, optical rotation, or magneto-optical effect of the medium to modulate the polarization state of light waves.

[0151] Further, each of the second rays is assigned to a corresponding detection unit 4, including:

[0152] S231: Determine the category of the second ray based on the index information of the second ray using a category mapping table or clustering algorithm; wherein the index information includes one or more of the following: wavelength index, phase index, and polarization index;

[0153] S232: The optical switch, adjustable mirror array, or controllable waveguide or fiber optic switching module of the detector 3 distributes the second light to the detection unit 4 corresponding to the category of the second light.

[0154] In this example, the category mapping table defines the mapping relationship between indicators and categories in various cases, including: the mapping relationship between wavelength indicators and a category; the mapping relationship between phase indicators and a category; the mapping relationship between polarization indicators and a category; the mapping relationship between wavelength indicators and phase indicators and a category; the mapping relationship between phase indicators and polarization indicators and a category; the mapping relationship between wavelength indicators and polarization indicators and a category; and the mapping relationship between wavelength indicators, phase indicators, and polarization indicators and a category.

[0155] The K-means clustering algorithm uses the number of detection units 4 in detector 3 as the pre-specified number of clusters K. Data points are then iteratively assigned to the nearest cluster centers, with the cluster center positions continuously updated until convergence. For example, when processing the index information of the second ray, the wavelength, phase, and polarization indices of each second ray can be combined into a feature vector, which is then input into the K-means clustering algorithm as data points. Based on the preset K value, the rays are clustered into different categories.

[0156] In a preferred embodiment, each detection unit 4 detects the received measurement light to obtain the unit absorbance of each detection unit 4, including:

[0157] S31: The first detection unit 4 acquires a measurement function; wherein, the measurement function is as follows:

[0158] A = tlg(I0 / I); where I0 is the light intensity of the initial light, I is the light intensity of the measured light, and t is the absorbance adjustment coefficient under the index information corresponding to the first detection unit 4; the first detection unit 4 is one of at least one detection unit 4;

[0159] S32: The first detection unit 4 performs N calculations on the initial light emitted N times and the first measurement light generated N times through the measurement function to obtain N single absorbance values ​​of the first detection unit 4; where N is a natural number greater than or equal to 1.

[0160] S33: If the first detection unit 4 determines that there is an abnormal absorbance among the N single absorbance values, then delete the abnormal absorbance value among the N single absorbance values.

[0161] S34: If the first detection unit 4 determines that there is no abnormal absorbance among the M single absorbance values, then the average of the M single absorbance values ​​is taken as the unit absorbance of the first detection unit 4; where M is a natural number less than or equal to N and greater than or equal to 1.

[0162] In this example, the molar absorptivity of the medium varies at different wavelengths, and phase shifts or polarization state changes during light-medium interaction can introduce measurement errors. Therefore, by setting different absorbance adjustment coefficients under different specifications, the accuracy of absorbance is greatly improved; and by removing abnormal absorbance, the accuracy of the subsequently obtained unit absorbance is ensured.

[0163] Further, if the first detection unit 4 determines that there is an abnormal absorbance among the N single absorbance values, it deletes the abnormal absorbance values ​​from the N single absorbance values, including:

[0164] S331: The first detection unit 4 calculates the Grubbs statistic for N single absorbance values;

[0165] S332: The first detection unit 4 determines N critical values ​​of the single absorbance based on the value of N and the preset significance level value;

[0166] S333: If the first detection unit 4 determines that the Grubbs statistic is not greater than the critical value, then the average absorbance is determined to be the unit absorbance of the first detection unit 4.

[0167] S334: If the first detection unit 4 determines that the Grubbs statistic is greater than the critical value, it takes the extreme value among the N single absorbances as the abnormal absorbance and calculates the Grubbs statistic for the N-1 single absorbances after deleting the abnormal absorbances; wherein, the extreme value is the single absorbance with the largest absolute difference between the N single absorbances and the mean of the N single absorbances.

[0168] Specifically, the Grubbs statistic for N single absorbance measurements is calculated, including:

[0169] The first detection unit 4 subtracts the extreme value among the N single absorbance values ​​from the mean value of the N single absorbance values ​​to obtain the first difference value;

[0170] The first detection unit 4 divides the absolute value of the first difference by the standard deviation of the N single absorbance values ​​to obtain the Grubbs statistic of the N single absorbance values.

[0171] In a preferred embodiment, the data processor 5 obtains the dosimeter absorbance based on the absorbance of at least one of the said units, including:

[0172] S41: The data processor 5 determines the index weight of the second detection unit 4 based on the index information of the second detection unit 4; wherein the second detection unit 4 is one of at least one of the detection units 4;

[0173] S42: The data processor 5 calculates the absorbance of at least one of the detection units 4 according to the index weights of at least one of the detection units 4 to obtain the absorbance of the dosimeter; wherein, the absorbance of the dosimeter is an absorbance value and / or an absorbance matrix; wherein, the absorbance value comprehensively reflects the overall absorbance of the dosimeter; each element value in the absorbance matrix is ​​the product of the index weight and its corresponding unit absorbance, and the element value reflects the absorbance of the dosimeter to the test light under a certain index information.

[0174] In this example, the data processor 5 analyzes the impact of each indicator on the detection results. For example, it determines the contribution of changes in wavelength, phase, and polarization to the dosimeter absorbance under different detection scenarios through experiments or theoretical models. If a change in an indicator has a significant impact on absorbance, it is assigned a larger weight; conversely, it is assigned a smaller weight. Taking into account the impact of each indicator, the data processor 5 determines the weights of indicators such as wavelength, phase, and polarization for each second detection unit 4. For example, for a detection unit 4 that is more sensitive to dose detection at a specific wavelength, the weight of its wavelength indicator may be relatively large.

[0175] Each detection unit 4 obtains its corresponding unit absorbance based on its own index information and detection principle. For example, under specific wavelength, phase, and polarization conditions, a certain detection unit 4 calculates the corresponding dose value by measuring the absorption or scattering characteristics of light, and then performs a weighted calculation on the absorbance of at least one unit.

[0176] By comprehensively considering information such as wavelength, phase, and polarization, and assigning them appropriate weights, the true condition of the detected object can be more accurately reflected. The influence of different indicators under different detection scenarios is reasonably represented, avoiding errors caused by a single indicator or simple averaging, thereby improving the detection accuracy of dosimeter absorbance.

[0177] Furthermore, the data processor 5 determines the index weights of the second detection unit 4 based on the index information of the second detection unit 4, including:

[0178] S411: The data processor 5 performs standardized processing on the unit absorbance of each detection unit 4 to obtain standardized data for each detection unit 4.

[0179] In this step, the standardization formula is: xij′=(max(xj)−min(xj)) / (xij−min(xj)) where min(xj) and max(xj) are the minimum and maximum values ​​of the j-th index, respectively, and xij′ is the standardized data of the absorbance of the i-th unit of the j-th index after standardization, and its value range is between [0,1].

[0180] For example, suppose that the indicator information includes wavelength, phase, and polarization indicators, and the specific indicators corresponding to wavelength, phase, and polarization are as follows:

[0181] Wavelength specifications: first wavelength and second wavelength;

[0182] Phase indicators: first phase and second phase;

[0183] Polarization parameters: first polarization and second polarization;

[0184] If the indicator information includes wavelength, phase, and polarization indicators simultaneously, then the indicator information will include eight cases: first wavelength, first phase, first polarization; first wavelength, second phase, first polarization; first wavelength, first phase, second polarization; first wavelength, second phase, second polarization; second wavelength, first phase, first polarization; second wavelength, second phase, first polarization; second wavelength, first phase, second polarization; second wavelength, second phase, second polarization.

[0185] S412: The data processor 5 determines the index entropy value of each index in the index information based on at least one of the standardized data; wherein the index entropy value reflects the importance of the index information.

[0186] In this step, the entropy value ej of each indicator is calculated using the formula ej = −k. Where k = 1 / ln(n), pij = xij′ / Where, ej is the entropy value of the j-th index; n is the number of detection units 4, which is the number of unit absorbances; xij′ is the standardized data of the i-th unit absorbance of the j-th index after standardization, and its value ranges between [0,1]. pij is the proportion of the i-th unit absorbance of the j-th index among all unit absorbances of the j-th index. For example, if the j-th index is the first wavelength, then xij′ is one of the following: the unit absorbance corresponding to the first wavelength, first phase, and first polarization; the unit absorbance corresponding to the first wavelength, second phase, and first polarization; the unit absorbance corresponding to the first wavelength, first phase, and second polarization; or the unit absorbance corresponding to the first wavelength, second phase, and second polarization. ej is the index entropy value of the first wavelength. The larger the index entropy value, the smaller the dispersion of the index, and the less information it provides.

[0187] S413: The data processor 5 determines the index weight of each detection unit 4 based on the entropy value of at least one index corresponding to each detection unit 4.

[0188] In this step, the weight wj of each indicator is calculated based on the entropy value, using the formula wj = (1 − ej) / Here, wj is the weight of the j-th indicator; ej is the entropy value of the j-th indicator. Based on the example above, wj will be the weights of the first wavelength, second wavelength, first phase, second phase, first polarization, and second polarization, respectively. Therefore, the larger the entropy value of an indicator, the smaller its corresponding indicator weight.

[0189] The entropy values ​​of at least one index corresponding to detection unit 4 are added together to obtain the preliminary weight of detection unit 4.

[0190] The initial weights of all detection units 4 are summed to obtain the initial total value;

[0191] Divide the initial weight of detection unit 4 by the initial total value to obtain the index weight of detection unit 4.

[0192] Further, the data processor 5 calculates the absorbance of at least one of the detection units 4 based on the index weights of at least one of the detection units 4 to obtain the absorbance of the dosimeter, including:

[0193] S421: The data processor 5 multiplies the unit absorbance of each detection unit 4 by its index weight to obtain the weighted dose result of each detection unit 4.

[0194] S422: The data processor 5 adds at least one of the weighted dose results to obtain an absorbance value, and uses the absorbance value as the absorbance of the dosimeter;

[0195] S423: The data processor 5 arranges each weighted dose result according to the number of its corresponding detection unit 4 to obtain an absorbance matrix, and uses the absorbance matrix as the absorbance of the dosimeter.

[0196] In this example, by multiplying the unit absorbance by its index weight and then adding them together to obtain the irradiation dose result, the obtained irradiation dose result can accurately reflect the absorbance of the measured light.

[0197] Meanwhile, by constructing absorbance values ​​and absorbance matrices, the absorbance of the dosimeter was evaluated from two dimensions: comprehensive and categorical, which greatly improved the accuracy of absorbance testing.

[0198] In a preferred embodiment, the data processor 5 obtains the irradiation dose result based on the dosimeter absorbance of the first measured light and the dosimeter absorbance of the second measured light, including:

[0199] S51: The data processor 5 acquires the difference function; the difference function is as follows:

[0200] S1 = m1 × A1 + n1;

[0201] S2 = m2 × A2 + n2;

[0202] ΔA = S1 – S2;

[0203] Where A1 is the dosimeter absorbance of the first measuring light and A2 is the dosimeter absorbance of the second measuring light;

[0204] m1 is the first adjustment coefficient corresponding to the temperature and humidity inside the radiation dose detection device when the first measuring light is formed, and m2 is the second adjustment coefficient corresponding to the temperature and humidity inside the radiation dose detection device when the second measuring light is formed.

[0205] n1 is the first bias value corresponding to the temperature and humidity inside the radiation dose detection device when the first measuring light is formed, and n2 is the second bias value corresponding to the temperature and humidity inside the radiation dose detection device when the second measuring light is formed.

[0206] S1 is the dosimeter absorbance of the first measuring light after adjustment for temperature and humidity factors, and S2 is the dosimeter absorbance of the first measuring light after adjustment for temperature and humidity factors.

[0207] ΔA is the irradiation dose result;

[0208] S52: When the first measuring light is formed in the irradiation dose detection device, the sensing device of the data processor 5 collects the first temperature value and the first humidity value in the irradiation dose detection device, and determines the first adjustment coefficient and the first bias value from the preset temperature and humidity mapping table based on the first temperature value and the first humidity value.

[0209] S53: When the second measuring light is formed in the irradiation dose detection device, the sensing device collects the second temperature value and the second humidity value in the irradiation dose detection device, and determines the second adjustment coefficient and the second bias value from the preset temperature and humidity mapping table based on the second temperature value and the second humidity value;

[0210] S54: The data processor 5 calculates the dosimeter absorbance of the first measuring light and the dosimeter absorbance of the second measuring light using the difference function to obtain the absorbance difference value;

[0211] S55: The data processor 5 obtains the irradiation dose result based on the absorbance difference and the preset conversion factor; wherein, the irradiation dose result is an irradiation dose value and / or an irradiation dose matrix; the irradiation dose value comprehensively reflects the irradiation value received by the dosimeter; each element value in the irradiation dose matrix describes the irradiation value received by the dosimeter in a dimension of index information.

[0212] In this example, the differences in the environmental conditions of the first and second measuring rays, the light source parameters of the light source device 1, and the measurement time will lead to different measurement conditions such as temperature and humidity inside the irradiation dose detection device. If the absorbance of the two dosimeters is directly subtracted, the accuracy of the determined irradiation dose result will be low due to the difference in measurement conditions.

[0213] In this example, the dosimeter absorbance of the first measuring light and the dosimeter absorbance of the second measuring light are corrected according to the first temperature value, the second temperature value, the first humidity value, and the second humidity value, respectively. This ensures that the final irradiation dose result takes into account the differences between the two measurement conditions, thus ensuring the accuracy of the final irradiation dose result.

[0214] The method for determining the conversion factor includes:

[0215] Obtain a raw dosimeter and place the raw dosimeter in the detection cell 2;

[0216] After the initial light emitted by the light source device 1 is detected in the original dosimeter of the initial light cell 2, the first test light is generated.

[0217] The detector 3 is used to receive the first test light and distribute the first test light to each detection unit 4;

[0218] Each of the detection units 4 detects the first measurement light it receives, and obtains the first unit absorbance of each of the detection units 4 respectively;

[0219] The data processor 5 is used to obtain the absorbance of the first test dosimeter based on the absorbance of at least one of the first units;

[0220] The original dosimeter is subjected to irradiation treatment to obtain a test dosimeter, and the test irradiation value of the irradiation treatment is obtained;

[0221] Place the test dosimeter in the detection pool 2;

[0222] After the initial light emitted by the light source device 1 is detected in the test dosimeter in the detection cell 2, a second test light is generated.

[0223] The detector 3 is used to receive the second test light and distribute the second test light to each detection unit 4;

[0224] Each of the detection units 4 detects the second measurement light it receives, and obtains the second unit absorbance of each of the detection units 4 respectively;

[0225] The data processor 5 is used to obtain the absorbance of the second test dosimeter based on the absorbance of at least one of the second units;

[0226] The data processor 5 obtains the difference in test absorbance based on the absorbance of the first test dosimeter and the absorbance of the second test dosimeter;

[0227] The data processor 5 constructs a test data from the test absorbance difference and the test irradiance value;

[0228] The test irradiance value and the test absorbance difference value in at least one of the test data are fitted to obtain a fitted straight line, and the slope of the fitted straight line is set as the conversion factor.

[0229] Example 2:

[0230] Please see Figure 2 This application provides an irradiation dose detection device, including: a light source device 1, a detection cell 2, a detector 3, and a data processor 5;

[0231] The light source device 1 is used to receive fluctuation amplitude information and fluctuation frequency information, and emit initial light to the detection cell 2 according to the fluctuation amplitude information and fluctuation frequency information. The initial light passes through the detection cell 2 and the dosimeter in the detection cell 2 to form a measurement light.

[0232] The detector 3 is used to receive the measurement light and distribute the measurement light to each detection unit 4; wherein, the detector 3 has at least one detection unit 4; each detection unit 4 is used to detect the measurement light it receives and obtain the unit absorbance of each detection unit 4; the unit absorbance reflects the absorbance of the dosimeter under different index information;

[0233] The data processor 5 is used to obtain the absorbance of the dosimeter based on the absorbance of at least one of the units;

[0234] The data processor 5 is further configured to obtain an irradiation dose result based on the dosimeter absorbance of the first measuring light and the dosimeter absorbance of the second measuring light; wherein, the first measuring light is the measuring light formed when the initial light passes through the dosimeter before irradiation; the second measuring light is the measuring light formed when the initial light passes through the dosimeter after irradiation; the irradiation dose result characterizes the difference in absorbance of the dosimeter before and after irradiation.
