[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] In the description of this application, the terms "first," "second," etc., are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the description of this application, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0025] It is important to note that ultraviolet (UV) radiation is electromagnetic radiation in the solar spectrum with wavelengths between visible light and X-rays, and it has significant impacts on human health and the ecological environment. Long-wave ultraviolet (UVA) radiation can penetrate deep into the skin and is a major factor contributing to skin aging; medium-wave ultraviolet (UVB) radiation mainly affects the skin's surface and easily causes sunburn; while short-wave ultraviolet (UVC) radiation is mostly absorbed by the ozone layer, artificially generated UVC plays a crucial role in scenarios such as medical disinfection. With the widespread application of ultraviolet radiation in environmental monitoring, industrial curing, medical disinfection, and electronics manufacturing, ultraviolet radiometers have become essential instruments for quantifying ultraviolet radiation intensity. Their calibration accuracy directly affects the reliability and validity of measurement results, thus impacting environmental assessments, industrial quality control, and the safety of medical procedures.

[0026] An ultraviolet (UV) radiometer is an optical measuring instrument used to measure ultraviolet (UV) radiation intensity. It detects the radiant energy in the ultraviolet band and converts it into an electrical signal, thereby achieving a quantitative characterization of UV radiation intensity. UV radiometers can accurately measure UV radiation intensity within specific wavelength ranges (such as UVA, UVB, and UVC). Due to their ease of operation, reliable performance, and low cost, UV radiometers are widely used in integrated circuits, aerospace, defense, industry and agriculture, medical and health care, electric light sources, and environmental protection, and are key equipment for ensuring the safety and effectiveness of UV radiation-related applications.

[0027] The measurement accuracy of an ultraviolet (UV) radiometer directly affects the reliability of UV radiation data. For example, in environmental monitoring, accurate measurement of UV radiation intensity is crucial for the scientific assessment of ozone layer depletion and UV environmental levels; in industrial production, precise control of UV curing dosage affects product quality and consistency; and in the medical field, the accuracy of UV disinfection dosage is closely related to disinfection effectiveness and personnel safety.

[0028] To ensure the accuracy and traceability of ultraviolet (UV) irradiance measurement data, UV calibrators must be performed before using them for UV irradiance measurements. Calibration eliminates errors in spectral response, sensitivity, and nonlinear response, ensuring that measurement results are consistent with the actual physical quantities. This allows the UV irradiance measurement results to be traceable to higher-level national or international metrological standards, thereby guaranteeing the comparability of results from different laboratories and using different measuring equipment.

[0029] Traditional ultraviolet irradiance meter calibration methods in related technologies typically include the absolute spectral irradiance method based on the light source and the absolute spectral power responsivity method based on the detector.

[0030] In the absolute spectral irradiance method based on light sources, a stable and reliable ultraviolet (UV) spectroradiometer is used as the transfer standard. The core process includes: first, the UV spectroradiometer is absolutely calibrated using a standard UV irradiance lamp group to obtain the spectral calibration coefficients; then, using the calibrated UV spectroradiometer, the spectral irradiance of the target UV light source is measured at a preset location, and the total irradiance of the target UV light source at a specified distance is calculated. Next, place the UV radiometer to be calibrated at the preset position mentioned above and measure the total irradiance of the target UV light source. Finally, the calibration correction factor was calculated through comparison. .

[0031] The detector-based absolute spectral power responsivity method uses the detector as a standard. The core process includes: first, measuring the relative spectral irradiance distribution of the target ultraviolet light source and the effective receiving area of ​​the detector; then, calculating the irradiance responsivity of the detector by measuring its absolute spectral power responsivity.

[0032] Place the UV radiometer to be calibrated under the target UV light source, measure the output current of the UV radiometer to be calibrated, and calculate the actual irradiance of the UV radiometer to be calibrated based on this current. .

[0033] Combined with the total irradiance of the target ultraviolet light source by the ultraviolet radiometer to be calibrated The calibration correction factor was calculated. .

[0034] While the aforementioned traditional UV irradiance meter calibration methods can meet the basic calibration requirements of UV irradiance meters to a certain extent, they still have the following significant drawbacks: First, both of these traditional UV irradiance meter calibration methods require further tracing to a higher-level metrological standard, involving multiple measurement transfers, which easily introduces measurement errors. For example, in the UVA band, the uncertainty of the absolute spectral irradiance method of the light source is approximately 2% (…). =1), the uncertainty of the detector's absolute spectral power responsivity method is approximately 3.9% ( =1).

[0035] Secondly, in the absolute spectral irradiance method based on light source, the spectroradiometer needs to drive the grating to scan the entire ultraviolet band point by point through a mechanical device. When the stability of the light source is insufficient, the fluctuation of the light source during the scanning process will directly affect the measurement results, resulting in insufficient calibration accuracy.

[0036] Furthermore, in the detector-based absolute spectral power responsivity method, the measurement of the detector's absolute spectral power responsivity relies on a higher-level standard detector, resulting in a long traceability chain. Errors accumulate at each level during transmission, and the accuracy of detector responsivity measurement in the ultraviolet band is relatively low, ultimately leading to a decrease in the reliability of the calibration results.

[0037] Finally, both of the aforementioned traditional ultraviolet radiometer calibration methods suffer from complex operational procedures and stringent environmental requirements. For example, the light source-based absolute spectral irradiance method requires that the measurement positions of the reference ultraviolet radiometer and the irradiance meter under test be perfectly aligned; otherwise, even a small deviation can cause significant measurement errors. In the detector-based absolute spectral power responsivity method, parameters such as the relative spectral distribution of the ultraviolet light source and the effective receiving area of ​​the detector need to be measured, and these processes are easily affected by ambient light and the stability of the light source.

[0038] Therefore, the above-mentioned traditional ultraviolet radiometer calibration methods have drawbacks such as long traceability chains, high measurement uncertainty, strong dependence on the environment, and complex operation.

[0039] To address this issue, this invention provides a calibration method for an ultraviolet (UV) radiometer based on a large-aperture WC-C fixed-point blackbody. The UV radiometer calibration method provided by this invention establishes an absolute reference through Planck's law of blackbody radiation, eliminating reliance on traditional transfer standards (standard lamp / reference detector) and achieving high-precision, traceable closed-loop calibration. Traditional UV light sources suffer from insufficient stability and poor uniformity, often resulting in significant differences in measurement results due to power level fluctuations. However, the large-aperture WC-C fixed-point blackbody possesses stable and accurate temperature characteristics, significantly improving measurement accuracy. Furthermore, the detector's relative spectral power responsivity and the UV light source's relative spectral irradiance distribution are easily and accurately measured, and the shape of the relative spectrum remains unchanged even with power fluctuations. Based on a large-aperture fixed-point blackbody, this invention only requires determining the detector's relative spectral power responsivity and the UV light source's relative spectral irradiance distribution to calibrate the UV radiometer.

[0040] The following is combined Figure 1 This invention describes the calibration method for an ultraviolet radiometer.

The imaging system images the exit of the integrating sphere to the monochromator entrance slit at a 1:1 magnification. The spectral irradiance of the target fixed-point blackbody can be calculated based on the following formula: (1) in, This represents the spectral irradiance of a blackbody at a fixed target point. Indicates the area of ​​the water-cooled aperture; This represents the distance between the water-cooled aperture and the entrance of the integrating sphere; This represents the wavelength of light emitted in a vacuum from a blackbody at a fixed target point.

[0050] Furthermore, compared to the uncalibrated ultraviolet radiometer at a wavelength of Absolute spectral power response in the radiation field of a target fixed-point blackbody And the ultraviolet radiometer to be calibrated at a wavelength of The absolute spectral power responsivity of the irradiated plane of the target ultraviolet light source The ultraviolet radiometer to be calibrated is at a wavelength of Relative spectral power response in the radiation field of a target fixed-point blackbody And the ultraviolet radiometer to be calibrated at a wavelength of The relative spectral power responsivity of the irradiation plane of the target ultraviolet light source Easy to measure accurately.

[0051] Optionally, in this embodiment of the invention, the target fixed point blackbody can be placed in a sealed box with a large-diameter opening. The radiation field of the target fixed point blackbody will be emitted through the large-diameter opening. Then, the ultraviolet radiometer to be calibrated can be placed in the radiation field of the target fixed point blackbody, which can improve the safety of the ultraviolet radiometer calibration method provided by the present invention.

[0052] Accordingly, the ultraviolet radiometer to be calibrated in this embodiment of the invention may include a detector probe and a display device. After placing the detector probe in the radiation field of the target fixed-point blackbody, the detector probe can collect the ultraviolet irradiance of the target fixed-point blackbody and send the collected ultraviolet irradiance to the display device. After receiving the ultraviolet irradiance sent by the detector probe, the display device can display the ultraviolet irradiance for the user to view. In this embodiment of the invention, the ultraviolet irradiance of the target fixed-point blackbody collected by the detector probe can be obtained through data interaction, and used as the original ultraviolet irradiance of the target fixed-point blackbody.

[0053] Step 102: Based on the spectral irradiance of the target fixed-point blackbody, the relative spectral irradiance distribution of the target ultraviolet light source, the relative spectral power responsivity of the ultraviolet radiometer to be calibrated in the radiation field of the target fixed-point blackbody, the relative spectral power responsivity of the ultraviolet radiometer to be calibrated on the irradiation plane of the target ultraviolet light source, and the original ultraviolet irradiance of the target fixed-point blackbody, calculate the target calibration factor of the ultraviolet radiometer to be calibrated, which is used to calibrate the ultraviolet radiometer to be calibrated.

[0054] Specifically, the spectral irradiance of the blackbody at the target fixed point is obtained. The relative spectral irradiance distribution of the target ultraviolet light source The ultraviolet radiometer to be calibrated is at a wavelength of Relative spectral power response in the radiation field of a target fixed-point blackbody The ultraviolet radiometer to be calibrated is at a wavelength of The relative spectral power responsivity of the irradiation plane of the target ultraviolet light source and the original ultraviolet irradiance of the blackbody at the target fixed point Subsequently, the target calibration factor of the UV radiometer to be calibrated can be calculated numerically. .

[0055] This invention, by introducing a target fixed-point blackbody as a radiation reference, effectively shortens the traceability chain of ultraviolet (UV) radiometer calibration, avoids error accumulation caused by multiple measurement transfers, and achieves high-precision, traceable absolute calibration. It effectively overcomes the measurement fluctuation problems caused by insufficient light source stability and poor spatial uniformity in traditional UV radiometer calibration methods, significantly improving the accuracy and consistency of UV radiometer calibration. This is based on the relative spectral power response of the UV radiometer to be calibrated in the blackbody radiation field, under the target UV light source, and the target UV light source. By combining the relative spectral irradiance distribution of the external light source with the original ultraviolet irradiance of the target fixed-point blackbody, the target calibration factor of the ultraviolet radiometer to be calibrated is calculated. This factor is then used to calibrate the ultraviolet radiometer. By utilizing the characteristics of the relative spectral power response under the target ultraviolet light source and the ease of accurate measurement of the relative spectral irradiance distribution of the ultraviolet light source, the accuracy and ease of operation of the ultraviolet radiometer calibration can be improved. This approach can better meet the urgent need for high-precision calibration of ultraviolet radiometers in fields such as environmental monitoring, industrial production, and medical applications.

[0056] As an optional embodiment, based on the spectral irradiance of the target fixed-point blackbody, the relative spectral irradiance distribution of the target ultraviolet light source, the relative spectral power responsivity of the ultraviolet radiometer to be calibrated in the radiation field of the target fixed-point blackbody, the relative spectral power responsivity of the ultraviolet radiometer to be calibrated on the irradiation plane of the target ultraviolet light source, and the original ultraviolet irradiance of the target fixed-point blackbody, a target calibration factor of the ultraviolet radiometer to be calibrated is calculated for calibration of the ultraviolet radiometer to be calibrated. This includes: calculating the spectral mismatch correction factor of the ultraviolet radiometer to be calibrated based on the spectral irradiance of the target fixed-point blackbody, the relative spectral irradiance distribution of the target ultraviolet light source, the relative spectral power responsivity of the ultraviolet radiometer to be calibrated in the radiation field of the target fixed-point blackbody, and the relative spectral power responsivity of the ultraviolet radiometer to be calibrated on the irradiation plane of the target ultraviolet light source; and calculating the original calibration factor of the ultraviolet radiometer to be calibrated based on the spectral irradiance of the target fixed-point blackbody and the original ultraviolet irradiance.

[0057] Specifically, the spectral irradiance of the blackbody at the target fixed point is obtained.

The specific formula for calculating the spectral mismatch correction factor of the ultraviolet radiometer to be calibrated based on the spectral irradiance of the target fixed-point blackbody, the relative spectral irradiance distribution of the target ultraviolet light source, the relative spectral power responsivity of the ultraviolet radiometer to be calibrated in the radiation field of the target fixed-point blackbody, and the relative spectral power responsivity of the ultraviolet radiometer to be calibrated on the irradiation plane of the target ultraviolet light source is as follows: (2) in, This represents the spectral mismatch correction factor of the ultraviolet radiometer to be calibrated; This represents the wavelength of the light emitted by the blackbody at the target fixed point in a vacuum; This represents the thermodynamic temperature of the blackbody at the target fixed point; This represents the spectral irradiance of the blackbody at the target fixed point; This indicates the wavelength of the light emitted by the target ultraviolet light source in a vacuum; This represents the relative spectral irradiance distribution of the target ultraviolet light source; This indicates the relative spectral power responsivity of the ultraviolet radiometer to be calibrated in the radiation field of the blackbody at the target fixed point; This represents the relative spectral power responsivity of the ultraviolet radiometer to be calibrated on the irradiation plane of the target ultraviolet light source; and This represents a predefined constant based on the photoelectric detection band range of the ultraviolet radiometer to be calibrated.

[0060] Specifically, when a UV-Vis irradiance meter calibrated using a target fixed-point blackbody is used to measure the irradiance generated by a target UV light source, measurement errors will occur due to spectral mismatch. Therefore, in this embodiment of the invention, a spectral mismatch correction factor is introduced to correct the aforementioned measurement errors caused by spectral mismatch.
