[0042] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0043] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] like Figure 1 As shown, the embodiment of the present application provides a method for detecting the focusing efficiency of a self-focusing lens array, which may include the steps of:

[0045] S1, obtaining the original light quantity of the target light source 1 through a near-field optical detector;

[0046] S2, moving the self-focusing lens array 2 to be tested to the target detection position, and determining the target image area after the target light source 1 passes through the self-focusing lens array 2 to be tested;

[0047] S3, based on the target image area, the near-field optical detector 3 is controlled to move to obtain the imaging light quantity of the self-focusing lens array 2 to be measured;

[0048] S4. Determine the focusing efficiency of the self-focusing lens array 2 to be tested based on the original light quantity and the imaging light quantity.

[0049] It should be noted that when obtaining the original light quantity, the self-focusing lens array 2 to be tested needs to be moved outside a certain range so that the near-field optical detector 3 can collect the complete original light quantity. Then the self-focusing lens array 2 to be tested is moved between the light source and the near-field optical detector 3, and the distance between the self-focusing lens array 2 to be tested and the target light source 1 can be determined according to the preset object distance, so as to simulate the actual use scenario for detection. By referring to the use scenario, the image plane area where the light is imaged after passing through the self-focusing lens array 2 to be tested can be determined, and then the near-field optical detector 3 is controlled to move on the image plane area, so as to collect the imaging light quantity after the light passes through the self-focusing lens array 2 to be tested. According to the values ​​of the original light quantity and the imaging light quantity, corresponding calculations are performed, for example, the imaging light quantity is divided by the original light quantity, and the focusing efficiency of the self-focusing lens array 2 to be tested can be obtained.

[0050] In the embodiment of the present application, the original light quantity of the light source is first collected, and then according to the product characteristics of the self-focusing lens array 2 to be tested and different usage scenarios, the array is moved to the corresponding detection position, and the corresponding image plane area is obtained, and then the near-field optical detector 3 is used to obtain the light quantity after passing through the array in the image plane area, so as to determine the focusing efficiency of the self-focusing lens array 2 to be tested. The embodiment of the present application can detect the focusing efficiency of the self-focusing lens array 2 to be tested according to its different usage scenarios.

[0051] In a possible embodiment, determining the target image plane area after the target light source 1 passes through the self-focusing lens array 2 to be tested includes:

[0052] Performing energy detection on the image formed after the target light source 1 passes through the self-focusing lens array 2 to be tested;

[0053] The target image area is determined according to the preset energy distribution range and energy detection results.

[0054] It should be noted that the energy detector can be used to perform energy detection after the light passes through the self-focusing lens array 2 to be tested. By performing energy detection on each area within a certain range behind the self-focusing lens array 2 to be tested, the energy value of each area can be obtained, and then the target image surface area to be detected can be determined based on the preset energy distribution range.

[0055] In an embodiment of the present application, by performing energy detection on the light after passing through the self-focusing lens array 2 to be tested, the target image surface area formed by the current detection scene can be determined based on a preset energy distribution range, thereby improving the diversity of the detection scenes and the versatility of the detection system.

[0056] In a possible embodiment, determining the target image plane area after the target light source 1 passes through the self-focusing lens array 2 to be tested includes:

[0057] The target image area is determined according to the preset imaging physical size.

[0058] It should be noted that, according to the preset imaging physical size, the image plane area corresponding to the imaging physical size can be determined after the light passes through the self-focusing lens array 2 to be tested, so that the focusing efficiency of the self-focusing lens array 2 to be tested can be tested based on this determined image plane area.

[0059] In an embodiment of the present application, the target image plane area is determined according to the specified imaging physical size, and the window for measuring the amount of light is limited, so as to obtain the focusing efficiency within the preset size range, thereby improving the diversity of detection scenes and the versatility of the detection system.

[0060] In a possible embodiment, determining the target image plane area after the target light source 1 passes through the self-focusing lens array 2 to be tested includes:

[0061] The target image area is determined according to the preset imaging energy distribution range and imaging distance.

[0062] It should be noted that the target image plane area can be directly determined according to the set imaging distance. For example, the use scenario of 1:1 imaging can be simulated, and the distance (imaging distance) between the target image plane area and the exit end of the self-focusing lens array 2 to be tested is set to be equal to the distance between the light source and the entrance end of the self-focusing lens array 2 to be tested.

[0063] In an embodiment of the present application, the target image area is determined according to the set imaging distance, so that the focusing efficiency at a specific distance is obtained according to the usage scenario, thereby improving the diversity of detection scenes and the versatility of the detection system.

[0064] See also Figure 2 , the embodiment of the present application also provides a detection system for the focusing efficiency of a self-focusing lens array, comprising an optical platform, a target light source 1, a self-focusing lens array to be tested 2, a near-field optical detector 3 and a control device 4;

[0065] The target light source 1, the self-focusing lens array 2 to be measured and the near-field optical detector 3 can be movably connected to the optical platform respectively;

[0066] The control device 4 is used to implement a method for detecting the focusing efficiency of any self-focusing lens array.

[0067] It should be noted that in actual applications, the target light source 1, the self-focusing lens array 2 to be tested, and the near-field optical detector 3 can be connected to the optical platform through a movable electric slide, and are electrically connected to the control device 4, so that the target light source 1, the self-focusing lens array 2 to be tested, and the near-field optical detector 3 can be controlled by the control device 4 and move relative to the optical platform within a certain range. It can be understood that the direction of movement includes but is not limited to lateral horizontal movement, longitudinal horizontal movement, and vertical movement. For example, the optical platform can be used as a reference to establish a spatial coordinate system, so that each component can move freely along the X, Y, and Z axes, respectively, and when moved to the set target detection position, each component can be controlled to remain relatively fixed with the optical platform. It should be noted that Figure 2 The self-focusing lens array 2 to be tested omits the lines connecting with the optical platform. The specific connection method can refer to the above method and be adaptively configured according to actual needs.

[0068] In the embodiment of the present application, the control device 4 controls each detection component to move or fix, so that the focusing efficiency of the self-focusing lens array 2 to be tested can be detected according to different usage scenarios.

[0069] In a possible embodiment, the self-focusing lens array focusing efficiency detection system further includes a light shield; the light shield is used to limit light other than the target light source 1 from entering the lens of the near-field optical detector 3 .

[0070] See also Figure 3 In an embodiment of the present application, the detection system also includes a light shield to avoid collecting ambient stray light and light leakage from the upper and lower sides of the array, thereby improving detection accuracy.

[0071] In a possible embodiment, the detection system of the focusing efficiency of the self-focusing lens array further includes a scattering sheet; the scattering sheet is used to convert the light output by the target light source 1 into scattered light with uniform energy distribution.

[0072] Please continue to see Figure 3 In an embodiment of the present application, the detection system also includes a diffuser that can diffuse the light from the light source to simulate a natural frame luminous scene, thereby improving the authenticity of the detection scene and thus improving the accuracy of the detection.

[0073] Based on the above-mentioned self-focusing lens array focusing efficiency detection system, the target light source 1 (such as a point light source) passes through a scattering sheet to generate a light source that simulates the light of a natural frame and generates a certain amount of light. When it does not pass through the array system, it approaches the lens of the near-field optical detector 3 to test the amount of light of the light source itself; then after the light source passes through the self-focusing lens array 2 to be tested, the near-field optical detector 3 is used to detect the amount of light reaching the image plane. Here, a light shield is used near the lens of the near-field optical detector 3 to shield ambient stray light and light leakage from the upper and lower sides of the self-focusing lens array 2 to be tested. In this way, (E′ / E) x 100% is obtained, which is used to measure the focusing efficiency, where E is the amount of light of the original light source, and E′ is the amount of light possessed by the imaging of the light source. The detection system of the embodiment of the present application can realize measurement according to the set energy distribution range or the specified physical size, so it can realize the detection of the energy range during 1:1 imaging according to the array principle and usage scenario.

[0074] It should be noted that since the self-focusing lens array is a relatively special product, it usually has the characteristics of small unit lens size, small aperture, non-axisymmetric product, short focal length, and short working distance. In addition, the product has been monopolized by foreign countries for a long time. Therefore, there is no ready-made equipment for the traditional optical detection instruments of the focusing efficiency of the self-focusing lens array in China to implement relevant tests, and the functions of the existing equipment are also limited. For the detection of self-focusing lens arrays, there is no ready-made equipment and instruments that can directly detect according to the array usage scenario.

[0075] In the prior art, optical power detectors are generally used for power detection, but power meters are usually used in scenarios where there are adapters or flanges as input signals. This detection method has the following disadvantages:

[0076] 1. Not suitable for the detection of spatial light at short working distance;

[0077] 2. Easily affected by ambient light, making the test inaccurate;

[0078] 3. Infrared, ultraviolet and visible light require switching of multiple sets of power meters;

[0079] 4. The photosensitive surface is large, and can only detect the integral size of the energy on the photosensitive surface. It cannot monitor the energy size during 1:1 imaging according to the array principle.

[0080] In view of the problems existing in the above-mentioned prior art, the embodiment of the present application provides a detection system for the focusing efficiency of a self-focusing lens array, which has the following beneficial effects:

[0081] 1. Achieved the indicators for testing the focusing efficiency of the self-focusing lens array;

[0082] 2. Achieved array indicators for testing object-image distances as short as 1-2 mm;

[0083] 3. Achieve direct measurement of focusing efficiency at the image plane;

[0084] 4. It can measure arrays with single lenses less than 1mm in diameter, or even 0.3mm (typical products on the market can be smaller);

[0085] 5. The focusing efficiency on the 1:1 imaging plane can be measured according to the array principle.
