[0002] Accurate testing of the optical performance of ambient lights is a crucial step in their production and R&D. Currently, common ambient light testing systems often suffer from insufficient accuracy when detecting spectral data.
[0003] Most existing detection systems use spectrometers with fixed installations, whose positions and angles are preset and cannot be flexibly adjusted. Because the spectrometer angle is fixed, it cannot be adapted to the actual light emission angle and contour of the ambient light, resulting in the spectrometer not achieving optimal matching with the light emitted by the ambient light during the detection process. Furthermore, some light may not enter the light-collecting window due to angular deviations, leading to incomplete spectral data acquisition and affecting the accuracy of the data.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Figure 11A schematic diagram of the structure of the second clamping mechanism in an embodiment of the present invention is shown. Figure 12 The diagram illustrates the cooperation between the trapezoidal boss and the support rod in an embodiment of the present invention. The ambient light detection system includes: a test base 1, a detection mechanism 2, and a fixing mechanism 3. The fixing mechanism 3 is mounted on the test base 1 and includes: a turntable 31 and multiple detection fixtures 32 disposed on the turntable 31. The turntable 31 rotates to rotate the multiple detection fixtures 32 one by one to below the detection mechanism 2. The detection mechanism 2 includes: a three-axis moving device 21, multiple spectrometers 4, and multiple light-collecting angle adjustment mechanisms 5. The multiple light-collecting angle adjustment mechanisms 5 are mounted on the three-axis moving device 21, and one spectrometer 4 is mounted on one light-collecting angle adjustment mechanism 5. Multiple spectrometers 4, driven by the three-axis moving device 21, simultaneously adjust their light-collecting positions above the fixed mechanism 3, or adjust their light-collecting positions sequentially. The light-collecting angle adjustment mechanism 5 includes a connecting seat 51, a first driving cylinder 52, and a mounting rod 53. One end of the mounting rod 53 is hinged to the output end of the first driving cylinder 52, the middle area of the mounting rod 53 is rotatably connected to the connecting seat 51, and the other end of the mounting rod 53 is fixedly connected to the spectrometer 4. Driven by the first driving cylinder 52, the mounting rod 53 swings around the connection point between the mounting rod 53 and the connecting seat 51 to autonomously adjust the light-collecting angle of the spectrometer 4 to conform to the ambient light's trajectory. In this embodiment, a rectangular coordinate system is set according to the multiple moving parts in the detection mechanism 2, wherein the width direction of the three-axis moving device 21 is the X-axis, the length direction of the three-axis moving device 21 is the Y-axis, and the height direction of the three-axis moving device 21 is the Z-axis.
[0021] The fixed mechanism 3 is equipped with a turntable 31 and two detection fixtures 32. The two detection fixtures 32 are symmetrically distributed based on the centerline of the turntable 31. The turntable 31 rotates 180° back and forth, so that the two detection fixtures 32 are alternately positioned below the detection mechanism 2, facilitating data collection by the spectrometer 44. While the turntable 31 rotates, the detection mechanism 2 and the spectrometer 4 are in a standby state, that is, they remain stationary in their original positions. Once the turntable 31 rotates to its final position, the detection mechanism 2 immediately begins to detect the detection fixture 32 below it, and the spectrometer 4 collects data simultaneously, achieving seamless connection of the detection process.
[0022] In this embodiment, the three-axis moving device 21 has movement functions in the X, Y, and Z axes, respectively. This allows the corresponding light-collecting angle adjustment mechanism 5 to move above the fixed mechanism 3, driving the spectrometer 4 to the most suitable light-collecting position. Furthermore, the three-axis moving device 21 is equipped with two spectrometers 4 and two light-collecting angle adjustment mechanisms 5. The three-axis moving device 21 can simultaneously drive both light-collecting angle adjustment mechanisms 5 to move, thereby adjusting the light-collecting position of the spectrometer 4. Specifically, the three-axis moving device 21 simultaneously drives the two light-collecting angle adjustment mechanisms 5 to move closer or further apart, thus shortening the stroke of one light-collecting angle adjustment mechanism 5, halving the distance of light-collecting angle adjustment, and halving the movement distance of the light-collecting angle adjustment mechanism 5. This also halves the movement distance of the spectrometer 4, reducing the detection distance required by the spectrometer 4. This eliminates the need for the spectrometer 4 to scan or sample over excessively long ranges during detection, thereby reducing the performance degradation and malfunction risk that may result from prolonged high-load operation of the spectrometer 4.
[0023] One end of the mounting rod 53 is hinged to the output end of the first driving cylinder 52. That is, when the first driving cylinder 52 outputs power, the output end of the first driving cylinder 52 extends along its working direction, pushing the mounting rod 53 to swing forward with the connection point between the mounting rod 53 and the connecting seat 51 as the center, thereby changing the detection angle of the spectrometer 4. Conversely, when the first driving cylinder 52 outputs power, the output end of the first driving cylinder 52 retracts along its working direction, causing the mounting rod 53 to swing backward with the connection point between the mounting rod 53 and the connecting seat 51 as the center, thereby changing the detection angle of the spectrometer 4. This changes the detection angle of the spectrometer 4 to adapt to the light emission angle of the ambient light to be detected and to adapt to the contour of the ambient light, achieving the best acquisition effect.
[0024] The spectrometer 4 is driven by the light-collecting adjustment mechanism to change its angle to adapt to the light emission angle and contour of the ambient light. This precise adaptation ensures that the light-collecting window of the spectrometer 4 and the light emitted by the ambient light reach the best matching state, avoiding problems such as light reflection, refraction loss or partial light not entering the spectrometer 4 due to angle deviation. This is beneficial for the spectrometer 4 to collect more complete and accurate spectral data.
[0025] Furthermore, an angle limiting block 54 is provided on one side of the connecting seat 51. The angle limiting block 54 includes a first sub-plate 541 and a second sub-plate 542, which are connected to each other to form an obtuse angle. A first fixing pin 543 is inserted into the first sub-plate 541, and a second fixing pin 544 is inserted into the second sub-plate 542. In this embodiment, the position of the first fixing pin 543 is the first working position of the lighting angle adjustment mechanism, and the position of the second fixing pin 544 is the second working position of the lighting angle adjustment mechanism. When the first drive cylinder 52 outputs power, its output end pushes the mounting rod 53 to rotate until the side wall of the mounting rod 53 abuts against the first fixing pin 543. The first fixing pin 543 exerts a force on the mounting rod 53, causing it to stop in the first working position. This allows the spectrometer 4 to collect data from a different angle, improving its acquisition effect. Similarly, when the first drive cylinder 52 outputs power, its output end drives the mounting rod 53 to rotate until the side wall of the mounting rod 53 abuts against the second fixing pin 544. The second fixing pin 544 exerts a force on the mounting rod 53, causing it to stop in the second working position. This allows the spectrometer 4 to collect data from a different angle, further improving its acquisition effect. The two different working positions allow the detection system to perform detection based on different light emission angles, adapting to the light emission angle of the ambient light to be detected and the contour of the ambient light, achieving optimal acquisition results.
[0026] Furthermore, the three-axis moving device 21 includes multiple Z-axis moving parts 213, multiple Y-axis moving parts 212, and an X-axis moving part 211. The multiple Y-axis moving parts 212 are movably mounted on the X-axis moving part 211, and one Z-axis moving part 213 is movably mounted on one Y-axis moving part 212. The multiple Y-axis moving parts 212 move closer to or further away from each other along the X-axis moving part 211. The spectrometer 4 is mounted on the Z-axis moving part 213 based on the light-collecting angle adjustment mechanism 5. The detection mechanism 2 includes two Z-axis moving parts 213, two Y-axis moving parts 212, and one X-axis moving part 211, wherein the two Y-axis moving parts 212 are movably mounted on the X-axis moving part 211, and one Z-axis moving part 213 is correspondingly mounted on one Y-axis moving part 212. The two Y-axis moving parts 212 move along the X-axis direction on the X-axis moving part 211 to ensure that the spectrometer 4 can cover the position of the ambient light to be detected. When the Y-axis moving part 212 moves along the Y-axis direction, it drives the corresponding Z-axis moving part 213 and the spectrometer 4 to move above the ambient light to be detected. The Z-axis moving part 213 drives the spectrometer 4 closer to the ambient light to be detected along the Z-axis direction, ensuring that the distance between the spectrometer 4 and the ambient light is within the optimal detection range, avoiding problems such as weak detection signal and large data error due to excessive distance, or interference to the spectrometer 4 due to excessive distance.
[0027] The two Y-axis moving parts 212 move closer to or further away from each other along the X-axis moving part 211, thereby shortening the travel distance of one Y-axis moving part 212 and halving the distance that one Y-axis moving part 212 moves in the X-axis direction, thus improving the data collection efficiency of the spectrometer 4. Similarly, the distance that the spectrometer 4 needs to detect is shortened, so that the spectrometer 4 does not need to scan or sample over an excessively long range during the detection process, thereby reducing the performance degradation and failure risk that the spectrometer 4 may cause due to long-term high-load operation.
[0028] Furthermore, the X-axis moving part 211 includes: a mounting bracket 2111, multiple parallel moving guide rails 2112, and multiple first driving components 2113; the multiple first driving components 2113 are disposed on the same side of the multiple moving guide rails 2112, and the first driving components 2113 are parallel to the moving guide rails 2112; a first slider 2114 is disposed on the top of any first driving component 2113, the multiple Y-axis moving parts 212 are mounted on the moving guide rails 2112, and one slider is fixedly connected to one Y-axis moving part 212; the second slider 2123 is moved along the length direction of the first driving component 2113 by the first driving component 2113, thereby driving the moving mechanism to move along the moving guide rails 2112. In this embodiment, the X-axis moving part 211 includes a mounting frame 2111, two parallel moving guide rails 2112, and two first driving components 2113. The two parallel moving guide rails 2112 are disposed on the upper end surface of the mounting frame 2111, and the two first driving components 2113 are also disposed on the upper end surface of the mounting frame 2111. The two first driving components 2113 are parallel to the moving guide rails 2112 and are located on the same straight line.
[0029] The two first driving components 2113 collide with each other based on the first slider 2114 on the moving part of the first driving component 2113, causing the multiple Y-axis moving parts 212 to collide with each other, which helps to reduce the risk of damage to the spectrometer 4 due to the collision of the moving parts. The first slider 2114 extends to form a connecting boss on the side near the Y-axis moving part 212. The connecting boss is connected to the corresponding Y-axis moving part 212. When the first slider 2114 is driven by the first driving component 2113 to move, it drives the Y-axis moving part 212 to move. That is, the two Y-axis moving parts 212 are driven by the two first sliders 2114 to move closer or further apart along the X-axis direction.
[0030] When the X-axis moving part 211 is in the initial position, the two Y-axis moving parts 212 are located at both ends of the X-axis moving part 211. When the X-axis moving part 211 is in the end position, the two Y-axis moving parts 212 are located at the center of the X-axis movement, that is, when the two Y-axis moving parts 212 approach each other, the two Y-axis moving parts 212 switch from the initial position to the end position. During this movement, the spectrometer 4 on the detection mechanism 2 collects data, which means that the spectrometers 4 at both ends simultaneously approach each other from both ends of the ambient light to detect the corresponding ambient light, reducing the detection distance and detection time, improving detection efficiency, and helping to improve the detection efficiency by more than 50%, thus achieving high-precision and high-efficiency detection.
[0031] It should be noted that the first driving component 2113 is a servo motor. The servo motor drives the first slider 2114 to move along the length direction of the top of the first driving component 2113, thereby driving the corresponding Y-axis moving part 212 to move along the length direction of the top of the first driving component 2113.
[0032] Furthermore, any one of the Y-axis moving parts 212 includes: a moving base 2121 and a second driving assembly 222 disposed on the moving base 2121; one side of the moving base 2121 is fixedly connected to the first slider 2114, and the bottom of the moving base 2121 is movably connected to the moving guide rail 2112 based on a connecting block; a second slider 2123 is disposed on the top of the second driving assembly 222, and the second slider 2123 is fixedly connected to one of the Z-axis moving parts 213; the second slider 2123 is moved along the length direction of the second driving assembly 222 by the second driving assembly 222, thereby driving the Z-axis moving part 213 to move. In this embodiment, a connecting groove is formed inwardly on the side of the moving base 2121 near the first slider 2114, and the connecting boss is inserted into the connecting groove, thereby strengthening the connection strength between the first slider 2114 and the moving base 2121, ensuring that the moving base 2121 can move when the first slider 2114 moves. The bottom of the movable base 2121 is provided with two connecting blocks, and the two connecting blocks are movably mounted on the two movable guide rails 2112 respectively. The two guide rails constrain the movable base 2121 from different positions, effectively dispersing various forces generated during the movement, such as inertial force and friction force, greatly reducing the swaying of the Y-axis moving part in the horizontal plane and the vertical offset, making the movement of the Y-axis moving part 212 along the Y-axis direction more stable.
[0033] The second driving component 222 is installed on the upper surface of the movable base 2121, and a second slider 2123 is provided on the top of the second driving component 222. A Z-axis moving part 213 is fixedly connected to the top of the second slider 2123. The second slider 2123 is driven by the second driving component 222 to move back and forth along the Y-axis direction, thereby adjusting the position of the spectrometer 4 and moving the spectrometer 4 directly above the ambient light to be detected for data collection.
[0034] When the Y-axis moving part 212 is in the initial position, the second slider 2123 is located at the end of the second driving component 222 closer to the first slider 2114; when the Y-axis moving part 212 is in the detection position, the second slider 2123 is located at the end of the second driving component 222 away from the first slider 2114. When the Y-axis moving part 212 moves from the initial position to the detection position, the second slider 2123 is moved along the Y-axis direction by the second driving component 222, so that the Z-axis moving part 213 is located directly above the ambient light to be detected, facilitating data acquisition by the spectrometer 4.
[0035] It should be noted that the second driving component 222 is a servo motor. The servo motor drives the second slider 2123 to move along the Y-axis, thereby driving the corresponding Z-axis moving part 213 to move back and forth along the Y-axis, so as to realize the Y-axis moving part 212 switching back and forth between the initial position and the detection position.
[0036] Furthermore, each of the Z-axis moving parts 213 includes a fixed base 2131 and a third driving assembly 2132 disposed on the fixed base 2131; a third slider 2133 is disposed on the third driving assembly 2132, and the third slider 2133 is driven by the third driving assembly 2132 to move along the height direction of the third driving assembly 2132; the light-collecting angle adjustment mechanism 5 is fixed on the third slider 2133, and the light-collecting angle adjustment mechanism 5 is driven by the third slider 2133 to move along the height direction of the third driving assembly 2132. In this embodiment, the fixed base 2131 is an L-shaped base, wherein the bottom of the fixed base 2131 (i.e., a horizontal plate arranged horizontally with the Y-axis) is fixedly connected to the top of the second slider 2123, and the side wall of the fixed base 2131 (i.e., a vertical plate arranged horizontally with the Z-axis) is fixedly connected to the third driving assembly 2132. The light-collecting angle adjustment mechanism 5 is located on the third slider 2133. When the third slider 2133 moves in the opposite direction along the Z-axis, it drives the light-collecting angle adjustment mechanism 5 and the spectrometer 4 to approach the ambient light that needs to be detected, so that the spectrometer 4 maintains a detection distance from the ambient light and achieves accurate data collection by the spectrometer 4.
[0037] When the Z-axis moving part 213 is in the initial position, the third slider 2133 is located at the top of the third driving assembly 2132. When the Z-axis moving part 213 is in the detection position, the third slider 2133 is located at the bottom of the third driving assembly 2132. When the Z-axis moving part 213 moves from the initial position to the detection position, the third slider 2133 moves along the Z-axis direction, causing the spectrometer 4 to move directly above the ambient light to be detected, and the spectrometer 4 maintains a suitable detection distance from the ambient light, facilitating data acquisition by the spectrometer 4.
[0038] It should be noted that the third driving component 2132 is a servo motor. The servo motor drives the third slider 2133 to move along the length direction of the top of the third driving component 2132, thereby driving the corresponding spectrometer 4 to move along the length direction of the top of the third driving component 2132.
[0039] Specifically, when detecting the ambient light, the second sliders 2123 in the two Y-axis moving parts 212 simultaneously move from their initial positions to the detection positions, that is, the Z-axis moving part 213 moves directly above the ambient light to be detected. Then, the third sliders 2133 on the two Z-axis moving parts 213 move from their initial positions to the detection positions, that is, the spectrometer 4 moves above the ambient light to be detected, with the output end of the spectrometer 4 facing the ambient light. Then, the two first driving components 2113 drive the two Y-axis moving parts 212 to move closer to each other, that is, drive the two spectrometers 4 to move closer to each other until the two first sliders 2114 move along the X-axis direction to the end of the corresponding first driving component 2113. During this movement, the spectrometer 4 simultaneously collects data from the ambient light. Then, the two first driving components 2113 drive the two Y-axis moving parts 212 to move away from each other, returning to their initial positions. Next, the third drive component 2132 drives the third slider 2133 to move upward along the Z-axis, so that the spectrometer 4 is away from the ambient light to be detected. Finally, the second slider 2123 moves in the opposite direction along the Y-axis to the initial position, so that the spectrometer 4 is away from the detection fixture 32, reducing the risk of collision between the turntable 31 and the spectrometer 4 when switching the detection fixture 32.
[0040] It should be noted that infrared sensors are provided on the X-axis moving part 211, the Y-axis moving part 212, the Z-axis moving part 213, and the light-collecting angle adjustment part. These infrared sensors are used to detect the moving distance of the three-axis moving parts or the swing angle of the light-collecting angle adjustment mechanism 5, thereby accurately moving the spectrometer 4 to the ambient light to be detected, improving the accuracy of data acquisition. Infrared sensors are existing technology, and their implementation principle will not be elaborated upon here.
[0041] Furthermore, the turntable 31 is provided with a plurality of detection fixtures 32, each of which is detachably mounted on the turntable 31, and an isolation mechanism 7 is provided between adjacent two detection fixtures 32. Each detection fixture 32 includes a fixture base 321, a fixture clamp 322, and a plurality of clamping mechanisms disposed on the fixture base 321, the plurality of clamping mechanisms being distributed around the fixture clamp 322. In this embodiment, the turntable 31 is provided with two detection fixtures 32, which are symmetrically distributed based on the centerline of the turntable 31, and an isolation mechanism 7 is provided between the two detection fixtures 32. That is, the isolation mechanism 7 coincides with the centerline of the turntable 31, and the height of the isolation mechanism 7 is higher than the height of the detection fixture 32, thereby preventing the light emitted by the two detection fixtures 32 from interfering with each other during detection, which is beneficial to improving the detection accuracy.
[0042] The tooling fixture 322 is mounted on the tooling base 321, and four clamping mechanisms are arranged around the tooling fixture 322. The four clamping mechanisms are divided into a first clamping mechanism 323 and a second clamping mechanism 324. The first clamping mechanism 323 is located at both ends of the tooling base 321 and is used to clamp the corresponding lamp head part of the ambient light. The second clamping mechanism 324 is located in the middle of the two first clamping mechanisms 323 and is used to clamp the corresponding light strip part of the ambient light.
[0043] It should be noted that the first clamping mechanism 323 includes a second driving cylinder 3231 and a rotating clamping rod 3232. The rotating clamping rod 3232 is located at the output end of the second driving cylinder 3231. When the second driving cylinder 3231 outputs power, it pushes the clamping block to clamp the corresponding lamp head part of the ambient light, fixing it on the tooling fixture 322. Conversely, when the second driving cylinder 3231 outputs power, it pushes the clamping block away from the corresponding part of the ambient light, making it convenient for workers to remove the ambient light from the tooling fixture 322. The second clamping mechanism 324 includes a third drive cylinder 3241 and a clamping swing arm 3242. The clamping swing arm 3242 is driven by the third drive cylinder 3241 to switch between a clamping state and a loosening state. When the third drive cylinder 3241 outputs power to push the clamping swing arm 3242 from the loosening state to the clamping state, the end of the clamping swing arm 3242 applies force from above to press the ambient light strip portion, fixing it on the tooling fixture 322. Conversely, when the third drive cylinder 3241 outputs power to pull the clamping swing arm 3242 from the clamping state to the loosening state, it is convenient for the operator to remove the ambient light from the tooling fixture 322.
[0044] Furthermore, the isolation mechanism 7 includes an isolation base 71 and an isolation plate 72. One end of the isolation base 71 is fixedly connected to the output end of the rotary motor 6, and the isolation plate 72 is mounted on the isolation base 71. In this embodiment, the isolation mechanism 7 includes two isolation bases 71 and two isolation plates 72. One isolation plate 72 is mounted on top of one isolation base 71, and the two isolation bases 71 are distributed along the center of the turntable 31, and are respectively located on both sides of the output end of the rotary motor 6. The isolation base 71, the output end of the rotary motor 6, and the isolation plate 72 together form a high wall to block the light emitted by the ambient light on the fixture, avoiding mutual interference between the light emitted by the ambient lights on the two fixtures, which would lead to inaccurate data collected by the spectrometer 4. This effectively solves the problem of mutual interference between ambient light rays during the detection process, and greatly improves the accuracy and reliability of the detection data.
[0045] It should be noted that the isolation plate 72 is black, which can effectively absorb the light emitted during ambient light detection and reduce the risk of mutual interference between the two ambient lights.
[0046] Furthermore, a rotary motor 6 is provided at the bottom of the turntable 31. The output end of the rotary motor 6 passes through the center of the turntable 31, and the turntable 31 is driven by the rotary motor 6 to rotate to switch the detection fixture 32. In this embodiment, the rotary motor 6 is placed on the test base 1, and the bottom of the rotary motor 6 is fixedly connected to the test base 1. The output end of the rotary motor 6 passes through the center of the turntable 31, and the output end is fixedly connected to the turntable 31. When the rotary motor 6 outputs power to drive the turntable 31 to rotate, it rotates only 180° each time, thereby switching back and forth between the two detection fixtures 32, and promptly switching to the next ambient light to be detected, improving detection efficiency.
[0047] It should be noted that the angle of rotation of the rotating motor 6 each time depends on the number of detection fixtures 32 set on the turntable 31. If there are three detection fixtures 32 on the turntable 31, the angle of rotation of the rotating motor 6 each time is 120°; if there are four detection fixtures 32 on the turntable 31, the angle of rotation of the rotating motor 6 each time is 90°, and so on.
[0048] Furthermore, the bottom of the turntable 31 is provided with a plurality of trapezoidal protrusions 311, which abut against a plurality of support rods 11 provided on the test base 1. In this embodiment, the bottom of the turntable 31 is provided with eight trapezoidal protrusions 311, which are distributed along the edge of the bottom of the turntable 31, and the included angle between two adjacent trapezoidal protrusions 311 is 45°. Similarly, the test base 1 is provided with eight support rods 11, one of which is positioned to cooperate with the trapezoidal protrusions 311. That is, the eight support rods 11 are distributed in a circle with the rotating motor 6 as the center, and the angle between two adjacent support rods 11 is also 45°. Each of the support rods 11 is provided with a ball bearing 111, which is located at the top of the support rod 11 and can roll in place at the top of the support rod 11. The trapezoidal boss 311 has two inclined surfaces and a spherical groove, with the two inclined surfaces symmetrically distributed based on the spherical groove. The inclined surfaces are used to reduce the resistance of the ball bearing 111 entering the spherical groove, and the spherical groove is used for... When the turntable 31 is driven by the rotary motor 6 to rotate to switch the detection fixture 32, that is, when the turntable 31 is driven by the rotary motor 6 to rotate 180°, the ball bearing 111 enters the spherical groove along the inclined surface, and is stuck after entering the spherical groove, thereby fixing the support rod 11 and the turntable 31 and reducing the risk of the turntable 31 rotating on its own.
[0049] It should be noted that inductive proximity switches are provided on the X-axis moving part 211, Y-axis moving part 212, Z-axis moving part 213, light-collecting angle adjustment mechanism 5 and turntable 31 in this invention. The inductive proximity switch in each component is connected to the drive component it is provided with, realizing automatic monitoring and automatic control of the equipment's operating status. Without frequent manual intervention, the equipment can automatically adjust the motion parameters of each component based on the position information fed back by the proximity switch.
[0050] In summary, this invention, by incorporating a light-collecting angle adjustment mechanism into the ambient light detection system, adjusts the angle of the spectrometer to adapt to the light emission angle and contour of the ambient light. This precise adaptation ensures that the light-collecting window of the spectrometer and the light emitted by the ambient light achieve optimal matching, enabling the spectrometer to collect more complete and accurate spectral data. Furthermore, this invention includes multiple Y-axis moving parts on the X-axis moving part, with these parts positioned far apart or close together. This shortens the movement distance of the spectrometer, improves its data collection efficiency, and reduces the detection distance required. This eliminates the need for the spectrometer to scan or sample over excessively long distances during detection, thereby reducing the risk of performance degradation and malfunctions that may result from prolonged high-load operation.
