Description

Technical Field

[0001] The invention relates to the field of optical element detection, in particular to an optical element detection system. Background Art

[0002] In the past, a beam quality analyzer was needed to detect whether an optical component was qualified. However, beam quality analyzers are expensive and not suitable for large-scale batch applications.

[0003] In order to solve the above technical problems, some engineers proposed a new detection scheme, which uses single-mode optical fiber to inject a Gaussian beam into an optical component, and then uses single-mode optical fiber to guide the output beam of the optical component into an optical power meter to determine whether the optical component is qualified. Since the beam energy of a single-mode optical fiber is approximately Gaussian in distribution, it can be called a Gaussian beam. The energy coupling efficiency of a Gaussian beam is very sensitive. As long as there is a problem with the optical component, the value detected by the optical power meter will be much smaller than the preset value. Since the cost of an optical power meter is much lower than that of a beam quality analyzer, this detection scheme is low-cost.

[0004] However, the above detection scheme is only applicable to detecting an optical element that emits one light beam, and cannot be used to detect an optical element that emits multiple light beams. Summary of the invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide an optical element detection system to solve the problem that the solution of using Gaussian beams to detect whether optical elements are qualified in the prior art is only applicable to detecting optical elements that only emit one light beam and has poor versatility.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0029] The embodiment of the present invention provides a detection system 1000 for an optical element, such as Figure 1-Figure 5 , as shown, the optical element detection system 1000 includes a light source 100, a first single-mode optical fiber 200, a plurality of converging lenses 310, a plurality of second single-mode optical fibers 400 and an optical power meter 500. The first single-mode optical fiber 200 includes a first input end 210 and a first output end 220 that are arranged opposite to each other, and the first input end 210 is located on the output light path of the light source 100. One of the converging lenses 310 is located on the output light path of the first output end 220, and the plurality of converging lenses 310 are arranged in a first direction ( Figure 1 The first direction is aligned with the incident direction of the converging lens 310 ( Figure 1 The plurality of second single-mode optical fibers 400 each include a second input end 410 and a second output end 420 that are disposed opposite to each other, and the plurality of second input ends 410 are respectively located on the outgoing light paths of the plurality of converging lenses 310. The optical power meter 500 is used to be connected to the second output end 420. The plurality of converging lenses 310 can be movably disposed so that the plurality of converging lenses 310 can be moved away from the incident light paths of the plurality of second input ends 410.

[0030] By implementing this embodiment, the light output by the light source 100 is incident on the first input end 210 of the first single-mode optical fiber 200, then emitted from the first output end 220 of the first single-mode optical fiber 200, then incident on the second input end 410 of the second single-mode optical fiber 400 through the converging lens 310, and then output from the second output end 420 of the second single-mode optical fiber 400 to the optical power meter 500.

[0031] When it is necessary to detect an optical element that outputs a beam of light, it is only necessary to place the optical element in the optical path between the first output end 220 and the converging lens 310, and compare the value measured by the optical power meter 500 with the preset value to determine whether the optical element is qualified. More specifically, when the measured value is not lower than the preset value, the optical element is determined to be qualified, and when the measured value is lower than the preset value, the optical element is determined to be unqualified.

[0032] refer to Figure 4 , taking the etalon 8000 (Etalon) as an example, the etalon 8000 includes two planes 8100, both of which have a certain reflectivity. The two planes 8100 will form a resonant cavity, and the light beam will reflect back and forth between them. For a qualified etalon 8000, the parallelism of the two planes 8100 must be very high. If the parallelism is not high enough, there will inevitably be a relatively large angle between the outgoing light and the incoming light, and the power measured by the optical power meter 500 will eventually be lower than the preset value.

[0033] When it is necessary to test an optical element capable of outputting multiple light beams, it is only necessary to first set the optical element in the optical path between the first output end 220 and the converging lens 310. The multiple light beams output by the optical element will enter the multiple second single-mode optical fibers 400 through the multiple converging lenses 310 respectively, and finally be output to the optical power meter 500 through the second output ends 420 of the multiple second single-mode optical fibers 400. The optical power meter 500 is first used to determine whether the power of each light beam is lower than a preset value. If it is lower than the preset value, the optical element is judged to be unqualified. If it is not lower than the preset value, the optical spacing qualified detection step is entered. In this step, the converging lens 310 needs to be removed. After the converging lens 310 is removed, the optical power will be attenuated. If the optical spacing of the output multiple light beams is qualified, the power attenuation rates of the multiple light beams should be similar. If the power attenuation rates of the multiple light beams are greatly different, the optical element is judged to be unqualified.

[0034] refer to Figure 3 Taking the beam splitter 9000 as an example, the beam splitter prism 9000 can split the incident light into two beams. If the two emitted beams have a large angle with the preset emission direction, the power finally measured by the optical power meter 500 will be lower than the preset value. If the power measured by the optical power meter 500 meets the standard, it is still necessary to determine whether the optical spacing between the two beams meets the standard. At this time, it is only necessary to move the converging lens 310 away. After the converging lens 310 is moved away, the optical power will attenuate. If the optical spacing between the two output beams is qualified, the power attenuation rates of the two beams should be similar.

[0035] It can be seen that the optical element detection system 1000 of the present invention is not only applicable to detecting an optical element that emits one beam of light, but also applicable to detecting an optical element that emits multiple beams of light.

[0036] It is worth mentioning that there are many specific implementations of the optical power meter 500 of this embodiment, which are not limited in this embodiment, as long as the power of the light beam output from the second output end 420 can be detected. For example, the optical power meter 500 is only provided with one, and the light power of different light beams can be identified by replacing the second single-mode optical fiber 400 connected to the optical power meter 500; for another example, the optical power meter 500 is provided with multiple, and each second output end 420 of the second single-mode optical fiber 400 is respectively connected to an optical power meter 500; for another example, the optical power meter 500 is a multi-channel optical power meter 500, and the multi-channel optical power meter 500 can be connected to the second output ends 420 of multiple second single-mode optical fibers 400, and the power of the light beams output by the multiple second single-mode optical fibers 400 can be identified.

[0037] refer to Figure 1-Figure 5 In a specific embodiment, the light source 100 and the first single-mode optical fiber 200 are provided with a plurality of first output ends 220, each of which is located on the output light path of the plurality of light sources 100, and the plurality of first output ends 220 are arranged in an array in the first direction, and the plurality of converging lenses 310 are located in the output direction of the plurality of first output ends 220. A plurality of optical power meters 500 are provided, and the plurality of optical power meters 500 are connected to the second output ends 420, respectively, or the optical power meter 500 is a multi-channel optical power meter 500, and the multi-channel optical power meter 500 is connected to the plurality of second output ends 420.

[0038] By implementing this embodiment, light emitted by several light sources 100 can be incident on several converging lenses 310 via several first single-mode optical fibers 200. Therefore, an optical element that outputs a light beam is arranged on the optical path between each first single-mode optical fiber 200 and the corresponding converging lens 310. This makes it possible to use the optical element detection system 1000 to simultaneously detect multiple optical elements that output a light beam.

[0039] Exemplarily, two of each of the light source 100 , the first single-mode optical fiber 200 , the converging lens 310 , and the second single-mode optical fiber 400 are provided, so that the optical element detection system 1000 can be used to simultaneously detect two etalons 8000 in the above embodiments.

[0040] It is worth mentioning that, as long as the number of converging lenses 310 and second single-mode optical fibers 400 is sufficient, this embodiment can also be used to simultaneously detect an optical element that outputs multiple light beams.

[0041] Exemplarily, there are four light sources 100, four first single-mode optical fibers 200, four converging lenses 310, and four second single-mode optical fibers 400, so that the optical component detection system 1000 can be used to simultaneously detect four etalons 8000 in the above-mentioned embodiments, and the optical component detection system 1000 can also be used to simultaneously detect two beam splitters 9000 in the above-mentioned embodiments. Of course, only two light sources 100 are needed to detect two beam splitters 9000, and the other two unnecessary light sources 100 can be turned off.

[0042] refer to Figure 1-Figure 5 In some embodiments, the optical element detection system 1000 further includes a first mounting seat 320 movably disposed at one side of the first output end 220 , and a plurality of converging lenses 310 are fixedly disposed on the first mounting seat 320 .

[0043] Specifically, since the plurality of converging lenses 310 in this embodiment are all fixed on the first mounting base 320, when all the converging lenses 310 need to be moved, only the first mounting base 320 needs to be moved. Compared with the embodiment in which the converging lenses 310 need to be moved one by one, this embodiment can effectively improve the moving efficiency of the plurality of converging lenses 310, and thus this embodiment can greatly improve the detection efficiency of the optical element detection system 1000.

[0044] It is worth mentioning that there are many implementations of the movable arrangement of the first mounting seat 320, which are not limited in this embodiment. Several embodiments are listed below for illustration.

[0045] In the first embodiment, the first mounting seat 320 is detachably arranged. When the converging lens 310 is needed, the first mounting seat 320 is mounted, and when the converging lens 310 is not needed, the first mounting seat 320 is removed.

[0046] refer to Figure 1-Figure 5 In a specific embodiment, the optical element detection system 1000 further includes a second mounting seat 610, which is disposed on one side of the first output end 220. A slot (not shown in the figure) is disposed on the side of the second mounting seat 610 facing the first output end 220, and the first mounting seat 320 is detachably inserted into the slot. With such a configuration, when a plurality of converging lenses 310 need to be used, the first mounting seat 320 is inserted into the slot to achieve the installation of the plurality of converging lenses 310. When the plurality of converging lenses 310 are not needed, the first mounting seat 320 is pulled out of the slot to achieve the removal of the plurality of converging lenses 310.

[0047] In the second embodiment: the optical element detection system 1000 also includes a linear drive component (not shown in the figure), which is connected to the first mounting base 320, and the linear drive component is used to drive the first mounting base 320 to move linearly, thereby enabling the plurality of converging lenses 310 to be moved away from the incident light path of the plurality of second input ends 410.

[0048] With such an arrangement, when the converging lenses 310 are not needed, the linear drive assembly can be used to move the converging lenses 310 away, and when the converging lenses 310 are needed, the linear drive assembly can be reset, which is very convenient.

[0049] refer to Figure 1-Figure 5 In some embodiments, a plurality of converging lenses 310 are integrally formed with the first mounting seat 320. Such a configuration can save the mold opening cost and assembly cost of the converging lenses 310 and the first mounting seat 320, and can also avoid the assembly error of the converging lenses 310 and the first mounting seat 320. It can be seen that the implementation of this embodiment not only makes the production cost of the optical element detection system 1000 lower, but also effectively improves the detection accuracy of the optical element detection system 1000, achieving multiple goals at one stroke.

[0050] Furthermore, the plurality of converging lenses 310 and the first mounting seat 320 are manufactured by a compression molding process, which requires only making a mold according to a pre-conceived structure, then melting the material and injecting it into the mold, and then cooling, annealing and demolding to obtain the imagined structural component.

[0051] refer to Figure 1-Figure 5 In some embodiments, the optical element detection system 1000 also includes a second mounting seat 610, which is arranged on one side of the first output end 220, and the second mounting seat 610 is provided with a plurality of first V-grooves 611, and a plurality of second input ends 410 are respectively mounted on the plurality of first V-grooves 611, and a plurality of converging lenses 310 are detachably mounted on the second mounting seat 610.

[0052] Specifically, the second mounting seat 610 of this embodiment can not only be used to position a plurality of second input terminals 410, but also can be used for installing a plurality of converging lenses 310. Compared with the embodiment in which two mounting seats (not shown in the figure) are set up, one mounting seat is used to position a plurality of second input terminals 410, and the other mounting seat is used for installing a plurality of converging lenses 310, the structure of this embodiment is simple and can effectively reduce the structural complexity of the optical element detection system 1000.

[0053] refer to Figure 1-Figure 5 In a specific embodiment, the optical element detection system 1000 further includes a first cover plate 700 , which is movably mounted on the top of the first V-shaped groove 611 to cooperate with the first V-shaped groove 611 to fix the second input end 410 .

[0054] Specifically, when the second input end 410 needs to be installed, the first cover plate 700 is first removed, the second input end 410 is placed in the first V-shaped groove 611 , and then the first cover plate 700 is covered. The first cover plate 700 and the first V-shaped groove 611 can be used to press the second input end 410 .

[0055] In a specific embodiment, the optical element detection system 1000 also includes a first lifting assembly (not shown in the figure), which is connected to the first cover plate 700. When the second input end 410 needs to be installed, the first lifting assembly is first used to lift the first cover plate 700. After the second input end 410 is placed in the first V-shaped groove 611, the first lifting assembly is used to lower the first cover plate 700 so that the first cover plate 700 can cooperate with the first V-shaped groove 611 to press the second input end 410.

[0056] In a specific embodiment, the first lifting assembly includes a first rotating drive member (not shown in the figure), a first screw rod (not shown in the figure), a first fixed seat (not shown in the figure) and a first movable seat (not shown in the figure). One end of the first screw rod is connected to the first rotating drive member so that the first rotating drive member can drive the first screw rod to rotate, the other end of the first screw rod is rotationally connected to the first fixed seat so that the first fixed seat can increase the stability of the first screw rod when it rotates, the first movable seat is threadedly connected to the first screw rod so that when the first screw rod rotates, the first movable seat can be driven to move along the first screw rod, and the first cover plate 700 is connected to the first movable seat so that when the first screw rod rotates, the first cover plate 700 can also move along the first screw rod. The advantage of this embodiment is that it can drive the first cover plate 700 to move with high precision, reducing the probability of crushing the second input end 410.

[0057] refer to Figure 1-Figure 5 In some embodiments, the optical element detection system 1000 further includes a third mounting seat 620 , which is disposed on a side of the converging lens 310 away from the second input end 410 , and a second V-groove 621 for mounting the first output end 220 is provided on the third mounting seat 620 .

[0058] Specifically, the second V-shaped groove 621 can be used to position the first output end 220 , thereby improving the detection accuracy of the optical element detection system 1000 .

[0059] refer to Figure 1-Figure 5 In a specific embodiment, the optical element detection system 1000 further includes a second cover plate 800 , which is movably mounted on the top of the second V-shaped groove 621 to cooperate with the second V-shaped groove 621 to fix the first output end 220 .

[0060] Specifically, when the first output end 220 needs to be installed, the second cover plate 800 is first removed, the first output end 220 is placed in the second V-shaped groove 621, and then the second cover plate 800 is covered. The second cover plate 800 and the second V-shaped groove 621 can be used to press the first output end 220 tightly.

[0061] In a specific embodiment, the optical element detection system 1000 also includes a second lifting assembly (not shown in the figure), which is connected to the second cover plate 800. When the first output end 220 needs to be installed, the second lifting assembly is first used to lift the second cover plate 800. After the first output end 220 is placed in the second V-shaped groove 621, the second lifting assembly is used to lower the second cover plate 800 so that the second cover plate 800 can cooperate with the second V-shaped groove 621 to press the first output end 220.

[0062] In a specific embodiment, the second lifting assembly includes a second rotating drive member (not shown in the figure), a second screw rod (not shown in the figure), a second fixed seat (not shown in the figure) and a second movable seat (not shown in the figure). One end of the second screw rod is connected to the second rotating drive member so that the second rotating drive member can drive the second screw rod to rotate, the other end of the second screw rod is rotationally connected to the second fixed seat so that the second fixed seat can increase the stability of the second screw rod when it rotates, the second movable seat is threadedly connected to the second screw rod so that when the second screw rod rotates, the second movable seat can be driven to move along the screw rod, and the second cover plate 800 is connected to the second movable seat so that when the second screw rod rotates, the second cover plate 800 can also move along the second screw rod. The advantage of this embodiment is that it can drive the second cover plate 800 to move with high precision, reducing the probability of crushing the first output end 220.

[0063] refer to Figure 1-Figure 5 In some embodiments, the optical element detection system 1000 further includes a base plate 630 , and the second mounting seat 610 and the third mounting seat 620 are both disposed on the base plate 630 and are integrally formed with the base plate 630 .

[0064] refer to Figure 1-Figure 5 By implementing this embodiment, the second mounting seat 610 and the third mounting seat 620 can be integrally formed, which can effectively reduce the mold opening cost and assembly cost, and can avoid assembly errors. It can be seen that by implementing this embodiment, not only the production cost of the optical element detection system 1000 is lowered, but also the detection accuracy of the optical element detection system 1000 can be effectively improved.

[0065] In some embodiments, the optical element detection system 1000 also includes a loading and unloading device (not shown in the figure), which is arranged between the first output end 220 and the plurality of converging lenses 310. The loading and unloading device is used to transport the optical element to the optical path between the first output end 220 and the plurality of converging lenses 310, and to transport the optical element that has completed detection away from the optical path between the first output end 220 and the plurality of converging lenses 310.

[0066] By implementing this embodiment, automatic loading and unloading of optical components can be realized, thereby effectively improving the detection efficiency of the optical component detection system 1000 and reducing the detection cost of the optical component detection system 1000 .

[0067] In a specific embodiment, the loading and unloading device includes a synchronous belt (not shown in the figure), a driving wheel (not shown in the figure), a driven wheel (not shown in the figure) and a rotating motor (not shown in the figure). The synchronous belt is arranged between the plurality of first output ends 220 and the plurality of converging lenses 310. The driving wheel is used to support the synchronous belt, the driven wheel is used to support the synchronous belt, the driven wheel and the driving wheel are arranged at intervals, and the rotating motor is connected to the driving wheel to drive the driving wheel to rotate.

[0068] By implementing this embodiment, as long as the rotating motor is started, it can drive the driving wheel to rotate. Since the driving wheel and the driven wheel cooperate to support the synchronous belt, the synchronous belt will be driven to run, so that the undetected optical elements on the synchronous belt can be moved to the optical path between the first output end 220 and the converging lens 310, and the optical elements that have completed detection can be removed from the optical path between the first output end 220 and the converging lens 310.

[0069] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the protection scope of the claims attached to the present invention.
