Description

Technical Field

[0001] This invention relates to the field of optical measurement technology, and in particular to a device and method for rapid measurement of immersion factor in underwater radiation sensor equipment. Background Technology

[0002] Underwater photosynthetically active radiation (EPA) sensors are used to measure the spectral irradiance levels available for phytoplankton photosynthesis. Regular calibration is required during use to ensure the accuracy and reliability of the measurement data. While factory calibration and metrological traceability of underwater EPA sensors are performed in an air environment, the difference in optical refractive index between air and water alters the original instrument response when the sensor is immersed underwater. This necessitates correcting the original calibration coefficients, which become known as the immersion factor.

[0003] Patent CN114674429 discloses a measuring device and method. In practice, it has been found that while the device can effectively measure the immersion factor, its operation is cumbersome, the measurement speed is relatively slow, and the method consumes a large amount of ultrapure water or standard seawater, resulting in high overall operating costs. Patent CN118243221 discloses another device and method for measuring the immersion factor. In practice, this method also suffers from high water consumption and even slower measurement speed. This is because it requires multiple adjustments to the water depth during use, and after each adjustment, an additional period of settling is needed for the liquid surface to return to calm before measurement. This significantly extends the total measurement time, resulting in low measurement efficiency and making it unsuitable for batch testing. These drawbacks lead to low measurement efficiency, cumbersome operation, and high measurement costs. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a rapid measurement device and method for immersion factor of underwater radiation sensor equipment, which solves the problems of low measurement efficiency, cumbersome operation and high water consumption in existing immersion factor measurement methods.

[0005] To achieve the above and other related objectives, the present invention provides the following technical solution:

[0007] The matting adapter ring has a first port that can form a thin water layer inside under the action of the dropper. The aperture of the first port is not less than twice the diameter of the photosensitive surface of the sensor under test. The end of the matting adapter ring away from the first port has a second port that can be fitted onto the sensor under test.

Under the action of the dropper, a thin water layer can be formed inside the first port of the matting adapter ring. The diameter of the thin water layer is not less than twice the diameter of the photosensitive surface of the sensor under test, and the depth of the thin water layer is 0.5 times the diameter of the photosensitive surface of the sensor under test.

[0012] In one embodiment of the present invention, the computer is electrically connected to the sensor under test via a wire. The computer is used to collect the response value of the sensor under test and calculate the immersion factor of the sensor under test based on the response value data.

[0013] A rapid measurement method for the immersion factor of an underwater radiation sensor device, based on the aforementioned rapid measurement device for the immersion factor of an underwater radiation sensor device, includes the following steps: fixing the sensor under test to the light outlet of a secondary homogenizing integrating sphere using an extinction adapter ring, such that the photosensitive surface of the sensor under test faces the light outlet of the secondary homogenizing integrating sphere through the first port on the extinction adapter ring, at which point the photosensitive surface of the sensor under test is located within the first port; in a completely dark environment, acquiring the response value of the sensor under test and recording it as the first response value;

The pluggable end cap on the secondary homogenizing integrating sphere is opened, the dropper is inserted, and the liquid inside is injected into the first port on the extinction adapter ring. The water depth can be calculated based on the liquid volume and the size of the first port. The dropper is removed, the pluggable end cap is replaced, and the response value of the sensor under test is collected and recorded as the third response value. The immersion factor of the sensor under test is calculated based on the first, second, and third response values. The above steps are repeated to obtain multiple immersion factors. The average of these multiple immersion factors is taken as the final measured immersion factor of the sensor under test.

[0015] In one embodiment of the present invention, calculating the immersion factor of the sensor under test based on the first response value, the second response value, and the third response value includes: calculating the immersion factor of the sensor under test according to the following formula: ;in, The immersion factor of the sensor under test. The first response value. This is the second response value. This is the third response value. This represents the light transmittance at the gas-liquid interface. The refractive index is the liquid light attenuation coefficient. The water is deep.

[0016] As described above, the underwater radiation sensor device and method for rapid measurement of immersion factor of the present invention have the following beneficial effects: The present invention can achieve a uniform light field across the entire angle through the primary and secondary homogenizing integrating spheres in the uniform light source assembly, which can eliminate the error caused by the correction of the refraction solid angle with water depth, and also eliminates the need for precise optical path adjustment; The present invention can also quickly obtain an accurate immersion factor value by directly comparing the radiation value of a stable light source measured by the sensor under test in a fixed water depth and in air; Therefore, the present invention can simplify the measurement steps, reduce measurement errors, improve measurement efficiency, significantly reduce the consumption of ultrapure water or standard seawater, and reduce measurement costs, thereby solving the problems of low measurement efficiency, cumbersome operation, and high experimental water consumption in existing immersion factor measurement methods.

[0023] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0024] The first embodiment of the present invention relates to a device for rapid measurement of immersion factor in an underwater radiation sensor. Please refer to [link to relevant documentation]. Figures 1 to 3 The system includes a uniform light source assembly for providing a highly uniformly distributed light energy field to the photosensitive surface 702 of the sensor under test 7; a graduated dropper 5 for drawing a specified volume of liquid; an extinction adapter ring 6 fitted onto the front end of the sensor under test 7 and positioned in a thin water layer by the dropper 5; and a computer 8 for calculating the immersion factor of the sensor under test 7 based on its response value. The computer 8 is electrically connected to the sensor under test 7 via wires. The computer 8 supplies power to the sensor under test 7 and also acts as a data acquisition device to collect the response value of the sensor under test 7 and calculate the immersion factor of the sensor under test 7 based on the response value data. It should be noted that the sensor under test 7 in this embodiment is an underwater photosynthetically active radiation sensor. In practical applications, this invention can also measure the immersion factor of other underwater radiation sensors. Furthermore, the uniform light source assembly in this embodiment can achieve a highly uniformly distributed light energy field on the photosensitive surface 702 of the sensor under test 7 within a range of approximately 180 degrees in various angular directions.

[0025] exist Figure 1 In this embodiment, the uniform light source assembly includes a light source 1 for providing stable intensity light radiation, a primary homogenizing integrating sphere 3 for initially homogenizing the light radiation incident from the light source 1, and a secondary homogenizing integrating sphere 4 located to the side of the primary homogenizing integrating sphere 3 for secondary homogenizing the light radiation emitted from the primary homogenizing integrating sphere 3. The light source 1 is electrically connected to the constant current driving power supply 2 via wires. The light source 1 is used to provide stable intensity light radiation. In this embodiment, the bulb used for the light source 1 is a halogen bulb or a full-spectrum LED. To ensure that the light emission remains stable during the experiment, it is used in conjunction with the constant current driving power supply 2. In practical applications, the primary homogenizing integrating sphere 3, the secondary homogenizing integrating sphere 4, and the sensor under test 7 can all be mounted on the instrument rack 13 for easy assembly, adjustment, and fixation.

[0026] The primary homogenizing integrating sphere 3 is provided with a first light entrance for the light radiation emitted by the light source 1. The primary homogenizing integrating sphere 3 is also provided with a light transmission port 9 perpendicular to the first light entrance. The primary homogenizing integrating sphere 3 is connected to the second light entrance on the secondary homogenizing integrating sphere 4 through the light transmission port 9. It should be noted that the light source 1 is aligned with the first light entrance of the primary homogenizing integrating sphere 3. The primary homogenizing integrating sphere 3 is used to perform primary homogenization of the light radiation emitted from the light source 1. To reduce light loss, the inner diameter of the primary homogenizing integrating sphere 3 is 5 cm, and the main material of the inner wall coating is barium sulfate. The primary homogenizing integrating sphere 3 is also provided with a light-blocking plate 10 located between the first light entrance and the light transmission port 9.

[0027] The secondary homogenizing integrating sphere 4 is provided with a pluggable end cap 11 perpendicular to the second light inlet. The secondary homogenizing integrating sphere 4 is also provided with a light outlet 12 that is spatially collinear with the pluggable end cap 11 and can be tightly fitted with the first port 14. The diameter of the light outlet 12 is not less than twice the diameter of the photosensitive surface 702 of the sensor under test. It should be noted that the secondary homogenizing integrating sphere 4 is used to homogenize the light radiation emitted from the light-transmitting port 9 of the primary homogenizing integrating sphere 3. The inner diameter of the secondary homogenizing integrating sphere 4 is 5 cm, and the main material of the inner wall coating is also barium sulfate. Finally, a light field with highly uniform light energy distribution in various angular directions within a range of nearly 180 degrees is formed at the light outlet 12 of the secondary homogenizing integrating sphere 4, ensuring that the photosensitive surface 702 of the sensor under test receives consistent light energy in various angular directions within a range of nearly 180 degrees. In addition, the pluggable end cap 11 on the secondary homogenizing integrating sphere 4 has a coating of the same material and thickness as the inner wall of the integrating sphere.

[0028] exist Figure 2 In the process, the matting adapter ring 6 has a first port 14 on which a thin water layer can be formed inside under the action of the dropper 5. The aperture of the first port 14 is not less than twice the diameter of the photosensitive surface 702 of the sensor under test. The end of the matting adapter ring 6 away from the first port 14 has a second port 15 that can be fitted onto the sensor under test 7. The inner sidewall of the matting adapter ring 6 has a rubber watertight ring 16 that can match the body 701 of the sensor under test 7. It should be noted that the matting adapter ring 6 is circular and is entirely coated with black matting agent. Glossy finish; In actual measurement, the first port 14 at the top of the matting adapter ring 6 can be tightly fitted with the light outlet 12 of the secondary homogenization integrating sphere 4; The rubber watertight ring 16 can be tightly fitted with the body 701 of the underwater photosynthetically active radiation sensor being measured. The diameter of the rubber watertight ring 16 matches the outer diameter of the body 701 of the underwater photosynthetically active radiation sensor being measured, so that the matting adapter ring 6 and the body 701 of the underwater photosynthetically active radiation sensor being measured do not leak water. The mating seam can also be additionally covered with waterproof insulating tape.

[0029] When the extinction adapter ring 6 is fitted onto the front end of the sensor under test 7, the photosensitive surface 702 of the sensor under test 7 is located within the first port 14 of the extinction adapter ring 6. Under the action of the dropper 5, a thin water layer can be formed within the first port 14 of the extinction adapter ring 6. The diameter of the thin water layer is not less than twice the diameter of the photosensitive surface 702 of the sensor under test, and the depth of the thin water layer is 0.5 times the diameter of the photosensitive surface 702 of the sensor under test. It should be noted that after the second port 15 of the extinction adapter ring 6 is fitted onto the end face where the photosensitive surface 702 of the underwater photosynthetically active radiation sensor under test is located... The first port 14 of the extinction adapter ring 6 allows the white photosensitive surface 702 of the underwater photosynthetically active radiation sensor to be fully exposed. A small amount of ultrapure water or standard seawater can be injected through the dropper 5, thereby forming a thin water layer inside the first port 14 of the extinction adapter ring 6. This thin water layer is leak-proof through the rubber watertight ring 16. The dropper 5 is graduated and can draw a specified volume of liquid. This specified volume corresponds to the water depth of the thin water layer, ensuring that the liquid dripped into the first port 14 through the pluggable end cap 11 reaches the specified water depth.

[0030] The second embodiment of the present invention relates to a method for rapid measurement of immersion factor in an underwater radiation sensor device, the process of which is as follows: Figure 4 As shown, the specific steps are as follows:

[0031] Step 101: The sensor under test 7 is fixed to the light outlet 12 of the secondary homogenizing integrating sphere 4 by the extinction adapter ring 6, so that the photosensitive surface 702 of the sensor under test 7 is directly facing the light outlet 12 of the secondary homogenizing integrating sphere 4 through the first port 14 on the extinction adapter ring 6. At this time, the photosensitive surface 702 of the sensor under test 7 is located inside the first port 14.

[0032] Specifically, the white photosensitive surface 702 of the underwater photosynthetically active radiation sensor to be measured is aligned with the light outlet 12 of the secondary homogenization integrating sphere 4 through the first port 14 of the extinction adapter ring 6 and kept fixed on the instrument frame 13.

[0033] Step 102: In a completely dark environment, collect the response value of the sensor under test 7 and record it as the first response value.

[0034] Step 103: Light up light source 1 and preheat for N minutes. After light source 1 is working stably, the photosensitive surface 702 of the sensor under test 7 is covered by a light field with uniform light intensity. At this time, the response value of the sensor under test 7 is collected and recorded as the second response value.

[0035] Specifically, in this embodiment, N is 15. After the light source 1 is working stably, the photosensitive surface 702 of the underwater photosynthetic effective radiation sensor is covered by a uniform light field with the same light intensity in all directions within a range of nearly 180 degrees.

[0036] Step 104: Use dropper 5 to draw a specified volume of fresh ultrapure water or standard seawater, open the pluggable end cap 11 on the secondary homogenization integrating sphere 4, insert dropper 5, and inject the liquid in dropper 5 into the first port 14 on the extinction adapter ring 6. The water depth can be calculated based on the liquid volume and the size of the first port 14.

[0037] Specifically, in practical applications, the dropper 5 is first moistened with ultrapure water before use. After the liquid is added, the photosensitive surface 702 of the underwater photosynthetically active radiation sensor under test is still covered by a uniform light field with the same light intensity in all directions within a range of nearly 180 degrees. In practical applications, the diameter of the photosensitive surface 702 of the underwater photosynthetically active radiation sensor under test is 1 cm, the volume of the liquid injected by the dropper 5 is 1.6 ml, and the water depth of the thin water layer formed is 0.5 cm and the diameter is 2 cm.

[0038] Step 105: Remove the dropper 5, replace the pluggable end cap 11, and collect the response value of the sensor 7 under test, and record it as the third response value.

[0039] Step 106: Calculate the immersion factor of the sensor under test 7 based on the first response value, the second response value, and the third response value.

[0040] Specifically, the immersion factor of the sensor 7 under test is calculated according to the following formula: ;in, The immersion factor of the sensor under test. The first response value. This is the second response value. This is the third response value. This represents the light transmittance at the gas-liquid interface. The refractive index is the liquid light attenuation coefficient. For water depth;

[0041] Among them, the light transmittance at the gas-liquid interface The specific formula is: , For ultrapure water, the refractive index is the liquid refractive index. The value is 1.333. For standard seawater, The value can be provided by the standard seawater manufacturer or determined by a laboratory refractometer; there is also the liquid light attenuation coefficient. For ultrapure water, The value is 0.0013 / cm, which is for standard seawater. The values ​​can be provided by standard seawater manufacturers or measured using a laboratory spectrophotometer.

[0042] More specifically, for ultrapure water, such as water depth If the value does not exceed 1 cm or the diameter of the photosensitive surface of the sensor being measured does not exceed 2 cm, then the light attenuation effect of ultrapure water is extremely weak and can be ignored. The above formula can be simplified to: , This represents the light transmittance at the gas-liquid interface.

[0043] Step 107: Repeat the above steps to obtain multiple immersion factors. Take the average of the multiple immersion factors as the final immersion factor of the sensor 7 under test.

[0044] In summary, this invention achieves a uniform light field across the entire angle through the primary homogenizing integrating sphere 3 and the secondary homogenizing integrating sphere 4 in the uniform light source assembly. This eliminates errors caused by correcting for changes in the refractive solid angle with water depth and eliminates the need for precise optical path adjustment. Furthermore, this invention can quickly and accurately obtain the immersion factor value by directly comparing the radiation values ​​of the stable light source 1 measured by the sensor under test 7 in fixed water depths and air. Therefore, this invention simplifies the measurement steps, reduces measurement errors, improves measurement efficiency, significantly reduces the consumption of ultrapure water or standard seawater, and lowers measurement costs. This solves the problems of low measurement efficiency, cumbersome operation, and high experimental water consumption in existing immersion factor measurement methods.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
