Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1The embodiment of the present application provides a detection system for an optical waveguide, comprising: a posture adjustment module 2, a light source module, a shooting module 5 and a control module (not shown in the figure); the posture adjustment module 2 is used to place the optical waveguide 6 to be detected and adjust the spatial posture of the optical waveguide 6; the light source module comprises a light source 3 and a light adjustment component 4, the light source 3 is connected to the light adjustment component 4, and the light adjustment component 4 is used to adjust the direction of the light emitted by the light source 3 toward the optical waveguide 6; the shooting module 5 is used to shoot the optical waveguide 6 to obtain an optical waveguide image; the control module is communicatively connected with the posture adjustment module 2, the light source module and the shooting module 5, and is used to control the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6; control the light source module to emit light in a target direction toward the optical waveguide 6; obtain the optical waveguide image of the target direction light irradiated to the optical waveguide 6 obtained by the shooting module 5; and determine the rainbow pattern parameters of the optical waveguide 6 according to the target direction and the optical waveguide image corresponding to the target direction.

[0033] Exemplarily, the posture adjustment module 2, the light source 3, the light adjustment component 4, and the shooting module 5 can all be arranged on the bottom plate 1. The control module in the embodiment of the present application has a built-in image processing algorithm, based on which the image parameters can be determined according to the optical waveguide image captured by the shooting module 5.

[0034] The optical waveguide image obtained by photographing the optical waveguide 6 by the photographing module 5 may include the area and / or brightness value of the rainbow pattern formed by the optical waveguide 6 .

[0035] Furthermore, at least part of the photographing module 5 and the control module can be integrally arranged, for example, integrally arranged in the test device. The test device in the embodiment of the present application can be connected to an integrating sphere to obtain a rainbow spectrum. The test device can photograph the optical waveguide 6 through the provided photographing module 5 to obtain an optical waveguide image, and determine the rainbow parameters of the optical waveguide 6 according to the optical waveguide image and the direction of the corresponding light through the control module.

[0036] Exemplarily, the optical waveguide 6 to be detected may be an optical waveguide used in near-eye display devices such as augmented reality display devices and virtual reality display devices.

[0037] It can be understood that the rainbow pattern parameters can reflect the characteristics of the rainbow pattern formed by the optical waveguide 6 during imaging. The light adjustment component 4 adjusts the light source 3 to emit light in different directions, so that the light in different directions can irradiate the optical waveguide 6 at different angles, and form different rainbow patterns after diffraction by the optical waveguide 6. Different rainbow patterns correspond to different rainbow pattern parameters. Among them, the rainbow pattern parameters include at least one of the following: the position, angle, area size, color, brightness, etc. of the rainbow pattern.

[0038] In general, the evaluation rules for rainbow patterns are:

[0039] Rainbow efficiency = rainbow brightness / incident ambient light intensity;

[0040] Rainbow brightness refers to the brightness of the rainbow observed at the position of the observer's eyes, which is generally measured by professional testing equipment to ensure the accuracy and objectivity of the measurement. Incident ambient light illuminance refers to the illuminance of ambient light irradiated on the optical waveguide (such as a display screen or protective film), which is generally obtained by professional illuminance measurement equipment. In addition, illuminance describes the intensity of incident light from the light source to the surface of the optical waveguide, which is only related to the characteristics of the light source and has nothing to do with the surface characteristics of the object. The rainbow efficiency can generally be obtained by comparing the rainbow brightness with the incident ambient light illuminance. The higher the ratio of rainbow efficiency, the more obvious the rainbow phenomenon is and the greater the impact on the visual effect.

[0041] The optical waveguide detection system provided in the above embodiment includes: a posture adjustment module 2, a light source module, a shooting module 5 and a control module; the posture adjustment module 2 is used to place the optical waveguide 6 to be detected and adjust the spatial posture of the optical waveguide 6; the light source module includes a light source 3 and a light adjustment component 4, the light source 3 is connected to the light adjustment component 4, and the light adjustment component 4 is used to adjust the direction of the light emitted by the light source 3 toward the optical waveguide 6; the shooting module 5 is used to shoot the optical waveguide 6 to obtain an optical waveguide image; the control module is communicatively connected with the posture adjustment module 2, the light source module and the shooting module 5, and is used to control the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6; control the light source module to emit light in a target direction toward the optical waveguide 6; obtain the optical waveguide image of the optical waveguide 6 captured by the shooting module 5 and irradiated by the light in the target direction; and determine the rainbow pattern parameters of the optical waveguide 6 according to the target direction and the optical waveguide image corresponding to the target direction. In the embodiment of the present application, the control module can control the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6, and at the same time control the light adjustment component 4 to adjust the direction of the light emitted by the light source 3 toward the optical waveguide 6, so that the light source 3 can irradiate the optical waveguide 6 from different angles to accurately control the spatial orientation of the light source 3 irradiating the optical waveguide 6; the shooting module 5 is controlled to shoot the light in the target direction to obtain the optical waveguide image; and according to the target direction and the corresponding optical waveguide image, the rainbow pattern parameters of the optical waveguide 6 can be determined, so that the rainbow pattern detection of the optical waveguide 6 can be more objective and accurate.

[0042] In an exemplary embodiment, the light source 3 is a parallel light source, which is used to emit light from the side of the optical waveguide 6 to illuminate the optical waveguide 6; the camera module 5 is disposed on the light emitting surface of the optical waveguide 6 and is spaced apart from the light emitting surface of the optical waveguide 6.

[0043] Exemplarily, the light source 3 may be a parallel light source. The parallel light emitted by the light source 3 of the embodiment of the present application is closer to the light effect of sunlight, and at the same time, the angle of the parallel light is easier to quantify. Compared with the divergent light source mode in the related art, the embodiment of the present application can accurately quantify and control the light angle of the parallel light emitted by the light source 3.

[0044] In some embodiments, only a single light source 3 emitting parallel light may be used. The control module only needs to control the light adjustment component 4 to adjust the light emitted by the single light source 3, which can reduce the impact of multiple lights emitted by multiple light sources 3 on the quantified light angle. Compared with the multi-light source mode in the related art, the embodiment of the present application can more accurately quantify and control the light angle of the parallel light emitted by the light source 3.

[0045] It can be understood that the light emitting surface is the interface from which the light in the optical waveguide 6 is emitted. In the optical waveguide structure, the light is totally reflected at the interface between the core layer and the cladding layer and propagates along the core layer. When the light reaches the light emitting surface, it will be emitted from the light emitting surface. The light source 3 in the embodiment of the present application emits light from the side of the optical waveguide 6 to illuminate the optical waveguide 6, and the light irradiated to the optical waveguide 6 comes out from the light emitting surface of the optical waveguide 6. At this time, the shooting module 5 can capture the image of the optical waveguide where the light comes out from the light emitting surface of the optical waveguide 6.

[0046] In an exemplary embodiment, the light source module is disposed on the periphery of the posture adjustment module 2 , and the light adjustment component 4 can drive the light source 3 to rotate on the periphery of the posture adjustment module 2 to adjust the direction of the light emitted toward the optical waveguide 6 on the posture adjustment module 2 .

[0047] like Figure 1 As shown, the light source module includes a light source 3 and a light adjustment component 4 arranged on the periphery of the posture adjustment module 2. The light incident surface of the optical waveguide 6 is the interface where the light first enters the optical waveguide 6. Under the adjustment of the light adjustment component 4, the light source 3 can emit light in different directions toward the light incident surface of the optical waveguide 6, so that the light in different directions enters the optical waveguide 6 from the light incident surface of the optical waveguide 6 and then exits from the light exit surface of the optical waveguide 6. At this time, the shooting module 5 arranged on the light exit surface of the optical waveguide 6 can shoot the optical waveguide image of the light in different directions exiting from the light exit surface of the optical waveguide 6, so that the optical waveguide image including rainbow patterns can be obtained.

[0048] Exemplarily, the control module can adjust the relative position between the shooting module 5 and the optical waveguide 6 according to the preview image captured by the shooting module 5, so that the rainbow pattern formed by the optical waveguide 6 is imaged at the center of the optical axis of the shooting module 5, and then adjust the imaging focal length of the shooting module 5 so that the shooting module 5 can achieve a clear imaging effect.

[0049] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the posture adjustment module 2 may include: a fixing component 21, a first adjustment component 22 and a second adjustment component 23; the fixing component 21 is used to fix the optical waveguide 6; the first adjustment component 22 is connected to the fixing component 21 and is communicatively connected to the control module; when the control module controls the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6, the first adjustment component 22 is controlled to adjust the posture of the optical waveguide 6; the second adjustment component 23 is connected to the first adjustment component 22 and is communicatively connected to the control module; when the control module controls the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6, the second adjustment component 23 is controlled to adjust the position of the optical waveguide 6.

[0050] Exemplarily, the fixing component 21 is disposed above the first adjustment component 22, and is used to fix the optical waveguide 6. It is understandable that the fixing component 21 in the embodiment of the present application can be a crescent-shaped bracket. Before the optical waveguide 6 is detected, the optical waveguide 6 can be embedded in the crescent-shaped bracket to fix the optical waveguide 6.

[0051] The first adjustment component 22 is arranged above the second adjustment component 23, and the second adjustment component 23 is arranged on the bottom plate 1. When the control module controls the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6, the first adjustment component 22 can be controlled to adjust the posture of the optical waveguide 6. For example, the control module can realize the angle change in space by controlling the first adjustment component 22 to rotate in space. When the control module controls the posture adjustment module 2 to adjust the spatial posture of the optical waveguide 6, the second adjustment component 23 can be controlled to adjust the position of the optical waveguide 6. For example, the control module can control the second adjustment component 23 to move in different directions such as upward and downward to change the position of the optical waveguide 6. The embodiment of the present application can adjust the spatial posture of the optical waveguide 6 through the first adjustment component 22 and the second adjustment component 23, so that the light emitted by the light source 3 can irradiate the optical waveguide 6.

[0052] In an exemplary embodiment, Figure 2 As shown, the first adjustment component 22 is a multi-axis rotation platform; the multi-axis rotation platform can adjust the angle of the optical waveguide 6 on at least two axes; and / or the second adjustment component 23 is a multi-axis displacement platform; the multi-axis displacement platform can adjust the position of the optical waveguide 6 on at least two axes.

[0053] For example, Figure 2As shown, the first adjustment component 22 is a multi-axis rotating platform. The multi-axis rotating platform can adjust the angle of the optical waveguide 6 around at least two axes of the first axis, the second axis, and the third axis. Among them, the direction of the first axis, the direction of the second axis, and the direction of the third axis correspond to the axis directions indicated by A, B, and C, respectively. Specifically, the control module can control the multi-axis rotating platform to rotate around the first axis (A) to drive the optical waveguide 6 to roll or pan around the first axis (A); the control module can also control the multi-axis rotating platform to rotate around the second axis (B) to drive the optical waveguide 6 to pitch, roll or pan around the second axis (B); the control module can also control the multi-axis rotating platform to rotate around the third axis (C) to drive the optical waveguide 6 to yaw around the third axis (C). The embodiment of the present application controls the multi-axis rotating platform to rotate around at least two axes of the first axis (A), the second axis (B), and the third axis (C) through the control module, so that the optical waveguide 6 can show rolling, rolling, yaw and other motion postures, so that the angle of the optical waveguide 6 in space can be accurately controlled.

[0054] For example, Figure 2 As shown, the second adjustment component 23 is a multi-axis displacement platform. The multi-axis displacement platform can adjust the position of the optical waveguide 6 on the fourth axis, the fifth axis, and the sixth axis. Among them, the direction of the fourth axis, the direction of the fifth axis, and the direction of the sixth axis correspond to the axis directions indicated by X, Y, and Z, respectively. Specifically, the control module can control the multi-axis displacement platform to move left and right along the fourth axis (X) to drive the optical waveguide 6 to achieve left and right linear motion based on the current position; the control module can also control the multi-axis displacement platform to move forward and backward along the fifth axis (Y) to drive the optical waveguide 6 to achieve forward and backward linear motion based on the current position; the control module can also control the multi-axis displacement platform to move up and down along the sixth axis (Z) to drive the optical waveguide 6 to achieve up and down linear motion based on the current position. In the embodiment of the present application, the control module controls the multi-axis displacement platform to move along the direction of at least two axes of the fourth axis (X), the fifth axis (Y), and the sixth axis (Z), so that the optical waveguide 6 can achieve linear motion such as left and right, front and back, and up and down, so that the position of the optical waveguide 6 in space can be accurately controlled.

[0055] In an exemplary embodiment, Figure 3As shown, the light adjustment component 4 includes: a first motion mechanism and a second motion mechanism; the first motion mechanism includes an arc track 41 and a first drive mechanism 42; the arc track 41 is arranged on the periphery of the posture adjustment module 2; the first drive mechanism 42 is communicated with the control module; when the control module controls the light source module to emit light in a target direction toward the optical waveguide 6, the first drive mechanism 42 is controlled to drive the arc track 41 to rotate relative to the posture adjustment module 2; the second motion mechanism is arranged on the arc track 41, connected to the light source 3 and communicated with the control module; when the control module controls the light source module to emit light in a target direction toward the optical waveguide 6, the second motion mechanism is controlled to move along the arc track 41 to adjust the direction of the light emitted by the light source 3 toward the optical waveguide 6.

[0056] Exemplarily, when the control module controls the light source module to emit light in a target direction toward the optical waveguide 6, the direction of the light emitted by the light source 3 toward the optical waveguide 6 can be adjusted by controlling the first motion mechanism and the second motion mechanism. Specifically, the first motion mechanism includes an arc track 41 and a first drive mechanism 42. The second motion mechanism is arranged on the arc track 41, and the light source 3 is connected to the second motion mechanism; the control module can control the second motion mechanism to move along the arc track 41 to drive the light source 3 to move along the arc track 41; the control module can control the first drive mechanism 42 to drive the arc track 41 to rotate relative to the posture adjustment module 2, so as to drive the light source 3 to rotate relative to the optical waveguide 6, thereby adjusting the direction of the light emitted by the light source 3 toward the optical waveguide 6. The embodiment of the present application controls the position of the light source 3 moving on the arc track 41 by the control module, so as to accurately control the direction of the light emitted by the light source 3 toward the optical waveguide 6.

[0057] It is understandable that in the embodiment of the present application, two support rods (not shown) can be set on both sides of the posture adjustment module 2, the two sides of the arc track 41 are rotatably connected to the two support rods, and the first driving mechanism can be set on one of the support rods.

[0058] In an exemplary embodiment, Figure 3 As shown, the arc track 41 is provided with a tooth portion 411; the second motion mechanism includes: a gear 43 and a second drive mechanism 44; the gear 43 is meshed with the tooth portion 411; the second drive mechanism 44 is communicatively connected with the control module; the second drive mechanism 44 is used to drive the gear 43 to rotate; when the control module controls the light source module to emit light in a target direction toward the optical waveguide 6, the second drive mechanism 44 is controlled to drive the gear 43 to mesh with the tooth portion 411 so that the second motion mechanism moves along the arc track 41 to adjust the direction of the light emitted by the light source 3 toward the optical waveguide 6.

[0059] For example, the control module can control the second driving mechanism 44 to drive the gear 43 to rotate. During the rotation of the gear 43, the gear 43 alternately engages with the teeth in the tooth portion 411, so that the second motion mechanism moves along the arc track 41, thereby driving the light source 3 to move along the arc track 41, thereby adjusting the direction of the light emitted by the light source 3 toward the optical waveguide 6.

[0060] In an exemplary embodiment, Figure 3 As shown, the second motion mechanism includes a slider 45, which is connected to the gear 43 and the light source 3; when the control module controls the second driving mechanism 44 to drive the gear 43 to engage with the tooth portion 411, the slider 45 moves along the arc track 41, driving the light source 3 to move along the arc track 41.

[0061] Exemplarily, the light source 3 may include a light emitter 31 and a fixing bracket 32. A gear 43 is installed in a slider 45, and a second driving mechanism 44 is provided on one side of the slider 45. The light emitter 31 is installed on the slider 45 through the fixing bracket 32. The gear 43 is driven by the second driving mechanism 44 to rotate, driving the slider 45 to move along the arc track 41, thereby driving the light emitter 31 to move along the arc track 41 in a circular arc. In the process of the light emitter 31 moving along the arc track 41, the direction of the light emitted by the light emitter 31 toward the optical waveguide 6 is constantly changed.

[0062] In some embodiments, the shape of the tooth portion 411 can be semicircular. The gear 43 is driven to rotate by the second driving mechanism 44, so that the gear 43 and the teeth in the semicircular tooth portion 411 are continuously and alternately meshed, driving the slider 45 to perform a circular arc trajectory motion corresponding to any angle between 0° and 180°, so that the direction of the light emitted by the light source 3 can be adjusted from one side to the other side (i.e., 0° to 180°) in the horizontal direction of the optical waveguide 6, so that the angle of light from different directions irradiating the optical waveguide 6 can be quantified.

[0063] In an exemplary embodiment, Figure 4 As shown, the arc track 41 is provided with a guide portion 412; the guide portion 412 is arranged on one side of the tooth portion 411; the second motion mechanism includes: a limit assembly 46; the limit assembly 46 is connected to the slider 45, and when the slider 45 moves along the arc track 41, the limit assembly 46 abuts against the edge of the guide portion 412.

[0064] Exemplarily, the limit assembly 46 may be a pulley, and the number of pulleys may be 2, 4 or 6. Of course, the specific number of pulleys may be set according to actual conditions. Specifically, when the second drive mechanism 44 drives the gear 43 to rotate, the slider 45 moves along the arc track 41 following the gear 43, and at the same time, the limit assembly 46 connected to the slider 45 moves along the guide portion 412 following the gear 43. The limit assembly 46 in the embodiment of the present application abuts against the edge of the guide portion 412, so that the slider 45 can remain stable during the circular arc trajectory movement along the arc track 41, thereby improving the structural stability of the detection system.

[0065] The present application also provides a method for detecting an optical waveguide. Figure 5 As shown, the optical waveguide detection method includes steps S101 to S104.

[0066] Step S101: Controlling the posture adjustment module to adjust the spatial posture of the optical waveguide.

[0067] Specifically, the posture adjustment module can adjust the spatial posture of the optical waveguide under the control of the control module. For example, the spatial angle and / or position of the optical waveguide can be adjusted.

[0068] Step S102: Control the light source module to emit light in a target direction toward the optical waveguide.

[0069] The light source module can emit light in a target direction toward the optical waveguide under the control of the control module. Light from different directions will generally be diffracted to form rainbow patterns after entering the optical waveguide.

[0070] Step S103 , obtaining an optical waveguide image of the optical waveguide when the light in the target direction irradiates the optical waveguide.

[0071] The shooting module can shoot the light in the target direction irradiating the light waveguide under the control of the control module to obtain the light waveguide image. Specifically, when the light source module is controlled to emit light in a first direction to irradiate the light waveguide, the shooting module is controlled to shoot the light waveguide image of the light in the first direction irradiating the light waveguide; when the light source module is controlled to emit light in a second direction to irradiate the light waveguide, the shooting module is controlled to shoot the light waveguide image of the light in the second direction irradiating the light waveguide; thereby, light waveguide images of light in different target directions irradiating the light waveguide can be obtained.

[0072] Step S104: determining rainbow pattern parameters of the optical waveguide according to the target direction and the optical waveguide image corresponding to the target direction.

[0073] For example, by determining the rainbow pattern parameters of the optical waveguide according to the target direction and the optical waveguide image corresponding to the target direction, the optical waveguide can be inspected to optimize the design of the optical waveguide.

[0074] The optical waveguide detection method provided in the above embodiment includes: controlling the posture adjustment module to adjust the spatial posture of the optical waveguide; controlling the light source module to emit light in the target direction toward the optical waveguide; obtaining the optical waveguide image of the optical waveguide when the light in the target direction irradiates the optical waveguide; and determining the rainbow ripple parameters of the optical waveguide according to the target direction and the optical waveguide image corresponding to the target direction. The embodiment of the present application can control the posture adjustment module to adjust the spatial posture of the optical waveguide, and at the same time control the direction of the light emitted by the light source module toward the optical waveguide, so that the light emitted by the light source module can irradiate the optical waveguide from different angles to accurately control the spatial orientation of the light irradiating the optical waveguide; the optical waveguide image obtained by controlling the shooting module to shoot the light in the target direction irradiating the optical waveguide; and then according to the target direction and the corresponding optical waveguide image, the rainbow ripple parameters of the optical waveguide can be determined, so that the rainbow ripple detection of the optical waveguide can be more objective and accurate.
