Description

Technical Field

[0001] The present disclosure relates to a multi-aperture telecentric lens optical architecture and a method of operating the same.

Background Art

[0002] In the field of optical detection, in order to detect defects with a relatively small size, a lens with a large aperture is required to provide a high-resolution image. However, the depth of field corresponding to a lens with a large aperture is relatively shallow, resulting in abnormal detection of samples with a relatively large thickness. Conversely, in order to detect a sample with a relatively large thickness, a lens with a small aperture is required to provide a deep depth of field. However, the resolution corresponding to a lens with a small aperture is relatively low, and it is not possible to clearly image defects with a relatively small size.

[0003] Therefore, in order to obtain an image that satisfies the requirements of high resolution and deep depth of field, it is necessary for a plurality of groups of detection lenses to scan the sample sequentially, or to take a plurality of shots using different resolution settings. However, the above method has the disadvantages of too long detection time and increased volume of the detection device.

[0004] In view of this, how to provide a lens and a corresponding operation method that can solve the above problems is one of the problems to be solved in the current industrial research field.

[0012] In one embodiment of the present disclosure, the step of adjusting the operating distance of at least one of the plurality of lenses so as to expand the initial depth of field of the multi-aperture telecentric lens optical architecture to a third depth of field includes: fixing the operating distance of a first lens having a first depth of field; and adjusting the operating distance of a second lens so as to move the range of the second depth of field of the second lens.

[0015] In one embodiment of the present disclosure, the step of acquiring an image by a plurality of cameras respectively connected to the plurality of lenses is performed in the same step.

[0016] Another technical aspect of the present disclosure is a multi-aperture telecentric lens optical architecture including a plurality of lenses each including a diaphragm and an operating distance adjustment device, a housing joined to the plurality of lenses, and a plurality of cameras respectively connected to the plurality of lenses.

Effect of the Invention

[0017] In the above embodiment, the operation method of the multi-aperture telecentric lens optical architecture can adjust the plurality of diaphragms of the plurality of lenses independently, so that the plurality of lenses can each have a high resolution and a deep depth of field.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, a plurality of embodiments of the present invention will be disclosed in the drawings, and for the purpose of clear explanation, many practical details will be described in the following description. However, it should be understood that the plurality of practical details are not used to limit the present invention. That is, in some embodiments of the present invention, the plurality of practical details are not necessary. Further, in order to simplify the drawings, some conventional structures and elements are simply shown in the drawings. And, for clarity, the thicknesses of layers and regions in the drawings may be exaggerated, and elements with the same reference numerals in the description of the drawings represent the same elements.

[0020] FIG. 1 is a schematic diagram of a multi-aperture telecentric lens optical architecture 100 according to an embodiment of the present disclosure. The multi-aperture telecentric lens optical architecture 100 includes a plurality of lenses, a housing joined to the plurality of lenses, and a plurality of cameras. In this embodiment, two lenses and two cameras are taken as examples. The first lens 110A has a first aperture 112A and a first working distance adjustment device 114A. The second lens 110B has a second aperture 112B and a second working distance adjustment device 114B. The first camera 120A and the second camera 120B are respectively connected to the first lens 110A and the second lens 110B. The optical axis direction of the first lens 110A and the optical axis direction of the second lens 110B are separated by 90 degrees, but the present disclosure is not limited thereto.

[0021] The depth of field (DOF) means a relatively clear imaging range before and after the focus or focal plane of the camera. When the aperture of the lens is relatively small, it has a relatively deep depth of field and a relatively low resolution. When the aperture of the lens is relatively large, it has a relatively shallow depth of field and a relatively high resolution.

[0022] For example, the sample 200 has a first surface 202 and a second surface 204, and a small-sized defect is located on the second surface 204. When the resolution of a single detection lens is sufficient to analyze a small-sized defect, the corresponding depth of field cannot cover the first surface 202 and the second surface 204 simultaneously. When the depth of field of a single detection lens can cover the first surface 202 and the second surface 204 simultaneously, the corresponding resolution cannot clearly image a small-sized defect on the second surface 204. Here, the "deep depth of field" means the depth of field that can cover the first surface 202 and the second surface 204 of the sample 200 simultaneously. Here, the "high resolution" means the resolution that can detect and analyze a small-sized defect during imaging.

[0023] Generally, in order to clearly image defects of different sizes on the first surface 202 and the second surface 204 of the sample 200, it is necessary to scan the sample 200 in sequence with multiple groups of detection lenses, or take multiple shots using different resolution settings. However, the above method has the disadvantages that the time of the detection process is too long and the volume of the detection device increases.

[0024] Since the first aperture 112A of the first lens 110A and the second aperture 112B of the second lens 110B are independent of each other, the first lens 110A and the second lens 110B have different resolutions and depths of field, thereby enabling the requirements of high resolution and deep depth of field to be met simultaneously in a single shooting process. The corresponding operation method will be described in conjunction with FIGS. 3 to 6 hereinafter.

[0025] The first working distance adjustment device 114A of the first lens 110A and the second working distance adjustment device 114B of the second lens 110B can relatively move the ranges of the depths of field of the first lens 110A and the second lens 1120B. Thereby, in a single shooting process, the requirements of high resolution and deep depth of field can be met simultaneously. The corresponding operation method will be described in conjunction with FIGS. 7 to 11 hereinafter.

[0026] The housing 130 of the multi-aperture telecentric lens optical architecture 100 connects the first lens 110A and the second lens 110B integrally. Therefore, the relative positions of the first lens 110A and the second lens 110B do not change, and the relative positions of the first camera 120A and the second camera 120B do not change. That is, the multi-aperture telecentric lens optical architecture 100 of the present disclosure can provide different resolutions and depths of field without multiple shootings or using multiple independent lenses, and has the advantages of saving time and space.

[0027] FIG. 2 is a schematic diagram of a multi-aperture telecentric lens optical architecture 100a according to another embodiment of the present disclosure. The difference between the multi-aperture telecentric lens optical architecture 100a and the multi-aperture telecentric lens optical architecture 100 is that the number of lenses 110 and cameras 120 is three. The housing 130 integrally connects the first lens 110A, the second lens 110B, and the third lens 110C. The third lens 110C is connected to the third camera 120C. The optical axis directions of the first lens 110A and the third lens 110C are 90 degrees apart, but the present disclosure is not limited thereto.

[0028] In the following paragraphs, taking the multi-aperture telecentric lens optical architecture 100 in FIG. 1 as an example, the operation method of the multi-aperture telecentric lens optical architecture will be described. Therefore, the described structures and elements will not be further described.

[0029] FIG. 3 is a flowchart of an operation method 300 of a multi-aperture telecentric lens optical architecture according to an embodiment of the present disclosure. FIG. 4 is a schematic diagram of the operation method 300 of the multi-aperture telecentric lens optical architecture in FIG. 3. FIG. 5 is a schematic diagram of a sample of the operation method 300 of the multi-aperture telecentric lens optical architecture and the depth of field range. FIG. 6 is a schematic diagram of an image obtained by the multi-aperture telecentric lens optical architecture with the sample in FIG. 5.

[0030] As shown in FIG. 5, in this embodiment, the small-sized defect 410 is located on the second surface 404 of the sample 400, and the relatively large-sized defects are located on the first surface 402 and the third surface 406 of the sample 400. The operation method 300 of the multi-aperture telecentric lens optical architecture is used to focus a lens having a high resolution and a relatively shallow depth of field on the second surface 404 to obtain an image of the small-sized defect 410, and the imaging range of another lens having a relatively low resolution and a deep depth of field can cover the entire sample 400.

[0031] Please refer to FIG. 3. The operation method 300 of the multi-aperture telecentric lens optical architecture starts from a step 310 of adjusting the operating distance of at least one of the plurality of lenses. Subsequently to step 310, a step 320 of adjusting the operating distance of another one of the plurality of lenses can be selectively performed. Alternatively, subsequently to step 310, a step 322 of fixing the operating distance of another one of the plurality of lenses can be selectively performed.

[0032] Please refer to FIGS. 4 and 5. The first lens 110A in this embodiment is configured to image the small-sized defect 410, but the present disclosure is not limited thereto. In this step, by rotating the first operating distance adjusting device 114A to adjust the first operating distance WD1 of the first lens 110A, the first focus plane FP1 of the first lens 110A is substantially aligned with the second surface 404 of the sample 400, or at least the second surface 404 is covered by the first depth of field DOF1.

[0033] In one embodiment, the second working distance WD2 of the second lens 110B may be fixed according to the actual situation (step 322, FIG. 3). For example, a preset range of the second depth of field DOF2 can cover the entire sample 400. In another embodiment, the second working distance adjusting device 114B is rotated to adjust the second working distance WD2 (step 320, FIG. 3). The second focus plane FP2 of the second lens 110B is located approximately at the center of the sample 400. The position of the second focus plane FP2 of the second lens 110B is determined according to the height of the sample 400. The first focus plane FP1 and the second focus plane FP2 may overlap.

[0034] The step of adjusting the first working distance adjusting device 114A and the second working distance adjusting device 114B can change the relative distance between the internal lens groups of the first lens 110A and the second lens 110B and the sample 400. Since the first lens 110A and the second lens 110B are integrally connected via the housing 130, in step 310, the working distance can be adjusted without moving the entire lens or the camera connected to the lens, which has the advantage of saving space.

[0035] In step 310 above, the second lens 110B may be adjusted. Accordingly, steps 320 and 322 are changed to adjusting the first lens 110A. The order of steps 310, 320 or 322 can be adjusted.

[0036] Please refer to FIG. 3. Subsequently, a step 330 of adjusting the apertures of a plurality of lenses is performed so that the multi-aperture telecentric lens optical architecture simultaneously has different first and second resolutions and different first and second depths of field.

[0037] Please refer to FIGS. 4 and 5. In this step, the first aperture 112A of the first lens 110A is adjusted so that the first lens 110A has a first resolution and a first depth of field DOF1. The second aperture 112B of the second lens 110B is adjusted so that the second lens 110B has a second resolution and a second depth of field DOF2. The first aperture 112A is a large aperture, and the second aperture 112B is a small aperture. Since the first resolution is larger than the second resolution, the second depth of field DOF2 is larger than the first depth of field DOF1. The range of the first depth of field DOF1 is located within the range of the second depth of field DOF2. Here, the first resolution is the high resolution defined above, and the second depth of field DOF2 is the deep depth of field defined above. In other embodiments, the ranges of the first depth of field DOF1 and the second depth of field DOF2 may be discontinuous.

[0038] As shown in FIG. 5, since the range of the first depth of field DOF1 covers the second surface 404 of the sample 400, small-sized defects 410 can be imaged by the first lens 110A having the first resolution (high resolution). The range of the second depth of field DOF2 of the second lens 110B covers the first surface 402, the second surface 404, and the third surface 406 simultaneously. That is, the entire sample 400 can be imaged by the second lens 110B having the second depth of field DOF2 (deep depth of field).

[0039] Please refer to FIG. 3. Finally, in the same step, a step 340 of acquiring an image by a plurality of cameras respectively connected to a plurality of lenses is performed.

[0040] Please refer to FIGS. 4 and 6. In this step, the video acquired by the first camera 120A includes a high-resolution video of small-sized defect 410, and the video acquired by the second camera 120B covers the video of the entire sample 400. A telecentric lens can make the video magnification of different subject distances within the depth of field range of the subject approximately equal. Therefore, the video IM1 acquired by the multi-aperture telecentric lens optical architecture 100 with a plurality of lenses having independent apertures can meet the requirements of high resolution and deep depth of field of the subject. In FIG. 6, the synthesized video IM1 is exemplarily shown. The form of synthesis or processing between the videos acquired by the plurality of lenses of the multi-aperture telecentric lens optical architecture 100 is not used to limit the present disclosure.

[0041] According to the above, the operation method 300 of the multi-aperture telecentric lens optical architecture can independently adjust the first aperture 112A of the first lens 110A and the second aperture 112B of the second lens 110B, so that the first lens 110A and the second lens 110B can each have high resolution and deep depth of field of the subject. In this way, in a single shooting step, the requirements of high resolution and deep depth of field of the subject can be met simultaneously. Since the first lens 110A and the second lens 110B are integrally connected via the housing 130, the working distance can be adjusted without moving the entire lens or the camera connected to the lens. Therefore, the multi-aperture telecentric lens optical architecture 100 can provide different resolutions and depths of field of the subject without multiple shootings or using a plurality of independent lenses, which has the advantage of saving time and space.

[0042] FIG. 7 is a flowchart of an operation method 500 of a multi-aperture telecentric lens optical architecture according to another embodiment of the present disclosure. FIG. 8 is a schematic diagram of the operation method 500 of the multi-aperture telecentric lens optical architecture of FIG. 7. FIG. 9 is a schematic diagram of a sample of the operation method 500 of the multi-aperture telecentric lens optical architecture according to FIG. 8 and a depth of field range. FIG. 10 is a schematic diagram of the operation method of the multi-aperture telecentric lens optical architecture of FIG. 7. FIG. 11 is a schematic diagram of a sample of the operation method 500 of the multi-aperture telecentric lens optical architecture according to FIG. 10 and a depth of field range. FIG. 12 is a schematic diagram of an image obtained by the multi-aperture telecentric lens optical architecture with the sample in FIG. 11.

[0043] As shown in FIG. 10, in this embodiment, the sample 600 has a relatively high height, and when the resolution of a single lens meets the detection requirement, the corresponding depth of field cannot cover the height of the entire sample 600. Therefore, the operation method 500 of the multi-aperture telecentric lens optical architecture is used to expand the depth of field of the multi-aperture telecentric lens optical architecture 100.

[0044] Please refer to FIG. 7. The operation method 500 of the multi-aperture telecentric lens optical architecture starts from a step 510 of adjusting the operating distances of a plurality of lenses based on a reference plane so that the multi-aperture telecentric lens optical architecture has an initial depth of field.

[0045] Please refer to FIGS. 8 and 9. Based on the reference plane REF shown in FIG. 9, align the operating distance of the first lens 110A and the operating distance of the second lens 110B. As shown in FIG. 8, the first operating distance WD1 and the second operating distance WD2 of the first lens 110A and the second lens 110B are approximately equal, and the first lens 110A and the second lens 110B have the same initial focus plane FP0. In this step, the initial depth of field DOF0 of the multi-aperture telecentric lens optical architecture 100 corresponds to the first depth of field DOF1 of the first lens 110A and also corresponds to the second depth of field DOF2 of the second lens 110B. The reference plane REF may be any cross-section of the sample 600.

[0046] The first depth of field DOF1 and the second depth of field DOF2 in this embodiment are approximately equal, but the present disclosure is not limited thereto. For example, in other embodiments, the initial depth of field DOF0 corresponds to the sum after the first depth of field DOF1 of the first lens 110A and the second depth of field DOF2 of the second lens 110B are superimposed when the first depth of field DOF1 and the second depth of field DOF2 are not the same (not shown). For example, the initial depth of field DOF0 corresponds to the first depth of field DOF1 when the first depth of field DOF1 is greater than the second depth of field DOF2. The initial depth of field DOF0 corresponds to the second depth of field DOF2 when the second depth of field DOF2 is greater than the first depth of field DOF1.

[0047] Please refer to FIG. 7. Following the method 500 for operating the multi-aperture telecentric lens optical architecture, a step 520 of adjusting the sizes of the apertures of the plurality of lenses is performed.

[0048] Please refer to FIG. 8. In this step, based on the resolution required for the detection sample 600, the first aperture 112A of the first lens 110A and the second aperture 112B of the second lens 110B are adjusted. The size of the first aperture 112A and the size of the second aperture 112B may be the same or different.

[0049] Please refer to FIG. 7. Following the method 500 of operating a multi-aperture telecentric lens optical architecture, a step 530 is performed to adjust the operating distance of at least one of the plurality of lenses so as to expand the initial depth of field of the multi-aperture telecentric lens optical architecture to a third depth of field.

[0050] Please refer to FIGS. 10 and 11. In this embodiment, for step 530, an example is given of fixing the first operating distance WD1 of the first lens 110A and adjusting the second operating distance WD2 of the second lens 110B. The range of the second depth of field DOF2 of the second lens 110B moves downward relative to the range of the first depth of field DOF1. As shown in FIG. 11, the third depth of field DOF3 after the first depth of field DOF1 and the second depth of field DOF2 are superimposed can cover the height of the entire sample 600. That is, the range of the third depth of field DOF3 is larger than the range of the first depth of field DOF1 and also larger than the range of the second depth of field DOF2. In other embodiments, the first depth of field DOF1 and the second depth of field DOF2 may be discontinuous (not shown), so the third depth of field DOF3 is the sum of the first depth of field DOF1 and the second depth of field DOF2.

[0051] In another embodiment, step 530 (refer to FIG. 7) may be to adjust the first operating distance WD1 of the first lens 110A and adjust the second operating distance WD2 of the second lens 110B. For example, in step 510 (refer to FIG. 7), another reference plane located at the center of the height of the sample 600 is selected, and in step 520 (refer to FIG. 7), the range of the first depth of field DOF1 is moved upward relative to the reference plane REF, and the range of the second depth of field DOF2 is moved downward relative to the reference plane REF and the range of the first depth of field DOF1. That is, it is only necessary to ensure that the range of the third depth of field DOF3 can cover the height of the entire sample 600.

[0052] Please refer to FIG. 7. Finally, in the same step, a step 540 is performed to acquire an image by a plurality of cameras respectively connected to the plurality of lenses.

[0053] Refer to FIGS. 10 to 12. In this step, the video acquired by the first camera 120A includes the third surface 606 and the fourth surface 608 of the sample 600, and the video acquired by the second camera 120B includes the first surface 602 and the second surface 604 of the sample 600. A telecentric lens can make the video magnification of different subject distances within the depth of field range of the subject approximately equal. Therefore, the video IM2 acquired by the multi-aperture telecentric lens optical architecture 100 with a plurality of lenses having independent apertures can meet the requirements of high resolution and deep depth of field of the subject. FIG. 12 exemplarily shows the synthesized video IM2. The form of synthesis or processing between the videos acquired by the plurality of lenses of the multi-aperture telecentric lens optical architecture 100 is not used to limit the present disclosure.

[0054] According to the above, the operation method 500 of the multi-aperture telecentric lens optical architecture can independently adjust the first aperture 112A of the first lens 110A and the second aperture 112B of the second lens 110B, so that the first lens 110A and the second lens 110B can each have the required resolution and depth of field of the subject. In this way, in a single shooting step, the requirements of high resolution and deep depth of field of the subject can be met simultaneously. Since the first lens 110A and the second lens 110B are integrally connected via the housing 130, the working distance can be adjusted without moving the entire lens or the camera connected to the lens. Therefore, the multi-aperture telecentric lens optical architecture 100 can provide different resolutions and depths of field of the subject without multiple shootings or using a plurality of independent lenses, which has the advantage of saving time and space.

[0055] Although the present invention is disclosed in the embodiments as described above, the above-described embodiments are not used to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be based on what is defined by the scope of the patent application attached later.
