In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0021] The component that modulates the brightness of the light source is the attenuation plate, which is also called a neutral density filter. Different positions of the attenuation plate have different transmittances, which can achieve different optical powers and thus different light source brightness.

[0022] Currently, there is a need to calibrate the transmittance at different positions of the attenuation plate, that is, there is a need to calibrate the optical power after the light passes through the attenuation plate.

[0023] The visual method can be used to calibrate the transmittance of the attenuation sheet at different positions, but the visual method has low accuracy and is very easy to cause damage to the human eye. The image method can also be used to calibrate the transmittance of the attenuation sheet at different positions based on the grayscale change of the image, but the image method is highly subjective, the calibration efficiency is low, and the calibration position accuracy is not high, which cannot meet the high requirements of light source brightness adjustment.

[0024] Based on this, the present application provides an optical power testing system, the system includes: a light source, an attenuation plate, a rotating motor, a zero position sensor, an optical power meter and a control device; the attenuation plate includes a plurality of fan-shaped areas, different fan-shaped areas have different transmittances, and the rotating motor is used to drive the attenuation plate to rotate, so as to adjust the brightness of the light source by using the rotating motor and the fan-shaped areas with different transmittances. The optical power meter is used to collect the optical power of the light emitted by the light source after passing through the different fan-shaped areas of the attenuation plate, that is, the optical power meter realizes the subsequent calibration of the transmittance of different positions of the attenuation plate by collecting the optical power of the light after passing through the different fan-shaped areas of the attenuation plate. The zero position sensor is installed on the attenuation plate, that is, the zero position sensor is used to identify any position in the attenuation plate. The control device is used to control the rotating motor to drive the attenuation plate to rotate with the zero position sensor at the installation position of the attenuation plate as the starting position with the 0 pulse as the starting pulse, and the control device is used to obtain multiple optical powers corresponding to different fan-shaped areas after the attenuation plate rotates one circle with the starting position collected by the optical power meter; the control device is used to establish a corresponding relationship between the pulse of the rotating motor and the optical powers corresponding to the different fan-shaped area positions obtained by the optical power meter, that is, by using the zero position sensor as the 0 pulse of the rotating motor and as the starting position of the rotation of the attenuation plate, the association between the pulse of the rotating motor and the different fan-shaped area positions of the attenuation plate is achieved, combined with the optical powers collected at the different fan-shaped area positions corresponding to different pulses when the rotating motor drives the attenuation plate to rotate, thereby establishing a corresponding relationship between the pulse of the rotating motor and the optical powers at the different fan-shaped area positions, and subsequently by controlling the pulse of the rotating motor, the transmittance of the attenuation plate can be accurately determined, and the transmittance of the attenuation plate at different positions can be accurately calibrated.

[0025] In order to better understand the technical solution and technical effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1 , which is a schematic diagram of the structure of an optical power test system provided in an embodiment of the present application. The optical power test system provided in an embodiment of the present application includes: a light source 110, an attenuation plate 120, a rotating motor 130, a zero position sensor 140, an optical power meter 150 and a control device 160.

[0027] In the embodiment of the present application, the light source 110 is used to emit light, that is, the light source 110 generates illumination light. The attenuation sheet 120 includes a plurality of fan-shaped areas, and different fan-shaped areas have different transmittances. The transmittances of the plurality of fan-shaped areas may vary in a gradient, that is, the optical power of light after passing through different fan-shaped areas is different, so that the brightness of the light source 110 can be adjusted by using the attenuation sheet 120.

[0028] As an example, refer to Figure 1 As shown, the attenuation plate 120 includes eight sector-shaped areas.

[0029] The light from the light source 110 is captured by the optical power meter 150 after passing through the attenuation plate 120, that is, the optical power meter 150 is used to collect the optical power of the light emitted by the light source 110 after passing through different fan-shaped areas of the attenuation plate 120. In other words, the optical power meter 150 realizes the calibration of the transmittance at different positions of the attenuation plate 120 by collecting the optical power of the light after passing through different fan-shaped areas of the attenuation plate 120.

[0030] The rotating motor 130 is used to drive the attenuation plate 120 to rotate, so as to adjust the brightness of the light source 110 by using the rotating motor 130 and the fan-shaped areas with different transmittances.

[0031] In an embodiment of the present application, the zero position sensor 140 is installed on the attenuation plate 120, that is, the zero position sensor 140 is used to identify any position in the attenuation plate 120, so that the position marked by the zero position sensor 140 is used to assist in the subsequent calibration of the transmittance of different positions of the attenuation plate 120.

[0032] The control device 160 is electrically connected to the rotating motor 130 and the optical power meter 150 , and is used to control the rotating motor 130 and the optical power meter 150 .

[0033] The control device 160 can control the rotating motor 130 to use the 0 pulse as the starting pulse to drive the attenuation plate 120 to rotate with the installation position of the zero position sensor 140 at the attenuation plate 120 as the starting position. In other words, the attenuation plate 120 rotates with the installation position of the zero position sensor 140 at the attenuation plate 120 as the starting position, and the rotating motor 130 uses the zero position sensor 140 as the 0 pulse position when driving the attenuation plate 120 to rotate, that is, uses the zero position sensor 140 as the initial pulse position. The zero position sensor 140 can be used to determine the 0 pulse position of the rotating motor 130 and the starting position of the attenuation plate 120, thereby achieving the time synchronization between the operation of the rotating motor 130 and the rotation of the attenuation plate 120, which is convenient for the subsequent calibration of the transmittance of the fan-shaped area of ​​the attenuation plate 120.

[0034] The control device 160 can obtain multiple optical powers corresponding to different sector-shaped areas after the attenuation plate 120 rotates one circle from the starting position, which are collected by the optical power meter 150. That is, when the rotary motor 130 drives the attenuation plate 120 to rotate, the transmittance of the attenuation plate 120 to light will change in different sector-shaped areas during the rotation process. The optical power meter 150 can collect multiple optical powers corresponding to multiple sector-shaped areas after the attenuation plate 120 rotates one circle, thereby assisting in the subsequent calibration of the transmittance of different sector-shaped areas.

[0035] After obtaining the multiple optical powers corresponding to the multiple sector-shaped areas, the control device 160 can construct the corresponding relationship between the pulse of the rotating motor 130 and the optical powers corresponding to the different sector-shaped area positions obtained by the optical power meter 150 based on the pulse of the rotating motor 130 and the multiple optical powers. In other words, by using the zero position sensor 140 as the 0 pulse position of the rotating motor 130 and as the starting position of the rotation of the attenuation plate 120, the pulse of the rotating motor 130 and the different sector-shaped area positions of the attenuation plate 120 are associated, and the optical powers collected at the different sector-shaped area positions corresponding to the different pulses when the rotating motor 130 drives the attenuation plate 120 to rotate are combined, so as to construct the corresponding relationship between the pulse of the rotating motor 130 and the optical powers at the different sector-shaped area positions. Subsequently, by controlling the pulse of the rotating motor 130, the transmittance of the attenuation plate 120 can be accurately determined, and the transmittance of different positions of the attenuation plate 120 can be accurately calibrated.

[0036] As an example, the installation position of the attenuation plate 120 where the zero position sensor 140 is located is set to the 0 pulse position of the rotating motor 130, the control device 160 controls the rotating motor 130 to rotate, the optical power meter 150 starts to collect optical power and saves the optical power in real time, and the control device 160 obtains a corresponding relationship based on the optical power and the pulse, and the corresponding relationship can be a pulse optical power curve, refer to Figure 2 As shown, Figure 2 The horizontal axis is pulses, and the vertical axis is optical power. A specific algorithm can be used to process and calculate the pulse optical power curve, so as to obtain the pulses of the rotating motor 130 corresponding to each sector area of ​​the attenuation plate 120 and the corresponding optical power.

[0037] It can be seen that, through the correspondence between the pulse of the rotating motor 130 and the optical power at different fan-shaped area positions, the transmittance of the attenuation plate 120 can be determined by controlling the pulse of the rotating motor 130, and the pulse of the rotating motor 130 can be determined at 1 pulse, thereby greatly improving the calibration accuracy and resolution of the transmittance of the attenuation plate 120. The optical power test system provided in the embodiment of the present application can realize calibration by using the control device 160 only after setting multiple components, and automatically obtain the calibration results, thereby realizing efficient calibration of the transmittance of the attenuation plate 120.

[0038] In an embodiment of the present application, the control device 160 simultaneously controls the rotating motor 130 and the optical power meter 150 so that the rotating motor 130 rotates with the position of the zero position sensor 140 as the starting position, and the optical power meter 150 collects optical power with the position of the zero position sensor 140 as the starting position, thereby avoiding the calibration accuracy being affected by the time difference between the rotating motor 130 and the optical power meter 150.

[0039] In the embodiment of the present application, after the corresponding relationship between the pulse of the rotating motor 130 and the optical power at different fan-shaped area positions is established, the control device 160 can control the rotating motor 130 to drive the attenuation plate 120 to rotate from the starting position to the target fan-shaped area where the target optical power corresponding to the target pulse is located according to the corresponding relationship and the target pulse. In other words, the control device 160 can directly determine the target fan-shaped area where the target optical power of the attenuation plate 120 is located according to the corresponding relationship and the target pulse, thereby achieving precise control of the transmittance of the attenuation plate 120.

[0040] In the examples of this application, reference is made to Figure 3 As shown, the zero position sensor 140 can be installed in the edge area of ​​the attenuation plate 120. Specifically, it can be installed in the edge area of ​​any sector area in the attenuation plate 120.

[0041] In an embodiment of the present application, the optical power test system provided in the embodiment of the present application further includes: a first lens 171 and a second lens 172. The first lens 171 and the second lens 172 are arranged on both sides of the attenuation plate 120. The control device 160 controls the attenuation plate 120 to rotate between the first lens 171 and the second lens 172, and controls the optical power meter 150 to collect the optical power of the light passing through the second lens 172.

[0042] refer to Figure 4 As shown, the first lens 171 is used to convert the light emitted by the light source 110 into parallel light. After passing through the attenuation plate 120, the parallel light is converged into convergent light by the second lens 172, which is convenient for the optical power meter 150 to collect.

[0043] It can be seen that the optical power testing system provided in the embodiment of the present application has a simple structure, wherein the rotating motor is a built-in part of the optical detection system itself, and the optical power meter is capable of automatically measuring and saving the optical power data under a fixed time series. It is only necessary to develop a control program that controls the rotating motor and the optical power meter at the same time, so the cost is relatively low.

[0044] In summary, the present application provides an optical power testing system, the system comprising: a light source, an attenuation plate, a rotating motor, a zero position sensor, an optical power meter and a control device; the zero position sensor is installed on the attenuation plate, and the association between the pulse of the rotating motor and the positions of different fan-shaped areas of the attenuation plate is achieved by utilizing the zero position sensor as the 0 pulse of the rotating motor and as the starting position of the rotation of the attenuation plate, and the optical power collected at the positions of different fan-shaped areas corresponding to different pulses when the rotating motor drives the attenuation plate to rotate is combined to construct a corresponding relationship between the pulse of the rotating motor and the optical power at different fan-shaped area positions, and subsequently, by controlling the pulse of the rotating motor, the transmittance of the attenuation plate can be accurately determined, and the transmittance of different positions of the attenuation plate can be accurately calibrated.

[0045] Based on an optical power testing system provided in the above embodiment, an embodiment of the present application further provides an optical power testing method, and its working principle is described in detail below in conjunction with the accompanying drawings.

[0046] See also Figure 5 , which is a flow chart of an optical power testing method provided in an embodiment of the present application.

[0047] The optical power testing method provided in the embodiment of the present application is applied to the optical power testing system provided in the above embodiment. The optical power testing method provided in the embodiment of the present application includes the following steps: S101, the control device controls the rotating motor to use the 0 pulse as the starting pulse to drive the attenuation plate to rotate with the installation position of the zero position sensor on the attenuation plate as the starting position.

[0048] In an embodiment of the present application, the control device can control the rotating motor to use the 0 pulse as the starting pulse to drive the attenuation plate to rotate with the zero position sensor at the installation position of the attenuation plate as the starting position. In other words, the attenuation plate rotates with the zero position sensor at the installation position of the attenuation plate as the starting position, and the rotating motor uses the zero position sensor as the 0 pulse position when driving the attenuation plate to rotate, that is, uses the zero position sensor as the initial pulse position. The zero position sensor can be used to determine the 0 pulse position of the rotating motor and the starting position of the attenuation plate, thereby achieving time synchronization between the operation of the rotating motor and the rotation of the attenuation plate, which is convenient for subsequent calibration of the transmittance of the fan-shaped area of ​​the attenuation plate.

[0049] S102, the control device obtains a plurality of optical powers corresponding to different sector-shaped areas after the attenuation plate rotates one circle from the starting position, which are collected by the optical power meter.

[0050] In an embodiment of the present application, the control device can obtain multiple optical powers corresponding to different sector-shaped areas after the attenuation plate rotates one circle from the starting position, which is collected by the optical power meter. That is to say, when the rotary motor drives the attenuation plate to rotate, the transmittance of the attenuation plate to light will change in different sector-shaped areas during the rotation process. The optical power meter can collect multiple optical powers corresponding to multiple sector-shaped areas after the attenuation plate rotates one circle, thereby assisting the subsequent calibration of the transmittance of different sector-shaped areas.

[0051] S103, the control device constructs a corresponding relationship between the pulses of the rotating motor and the optical powers corresponding to the positions of different sector-shaped regions acquired by the optical power meter.

[0052] In an embodiment of the present application, after obtaining multiple optical powers corresponding to multiple sector-shaped areas, the control device can construct a correspondence between the pulse of the rotating motor and the optical powers corresponding to different sector-shaped area positions obtained by the optical power meter based on the pulse of the rotating motor and the multiple optical powers. In other words, by using the zero position sensor as the 0 pulse position of the rotating motor and as the starting position of the rotation of the attenuation plate, the pulse of the rotating motor and the positions of different sector-shaped areas of the attenuation plate are associated, and the optical powers collected at different sector-shaped area positions corresponding to different pulses when the rotating motor drives the attenuation plate to rotate are combined to construct a correspondence between the pulse of the rotating motor and the optical powers at different sector-shaped area positions. Subsequently, by controlling the pulse of the rotating motor, the transmittance of the attenuation plate can be accurately determined, and the transmittance of different positions of the attenuation plate can be accurately calibrated.

[0053] In the embodiment of the present application, after constructing the corresponding relationship between the pulse of the rotating motor and the optical power at different fan-shaped area positions, the control device can control the rotating motor to drive the attenuation plate to rotate to the target fan-shaped area where the target optical power corresponding to the target pulse is located from the starting position according to the corresponding relationship and the target pulse. In other words, the control device can directly determine the target fan-shaped area where the target optical power of the attenuation plate is located according to the corresponding relationship and the target pulse, thereby realizing precise control of the transmittance of the attenuation plate.

[0054] In an embodiment of the present application, the control device controls the attenuation plate to rotate between the first lens and the second lens, and controls the optical power meter to collect the optical power of the light passing through the second lens.
