Optical splitter detection system and detection method

Abstract

The invention is applicable in the technical field of detection, and provides an optical splitter detection system for detecting whether an optical splitter has a broken line area. The optical splitter detection system comprises a light-emitting device and an image detection device which are connected with each other, wherein the light-emitting device irradiates light onto the optical splitter, and the image detection device collects light exiting from the optical splitter to form a detection image, and judges whether the optical splitter has the broken line area according to the detection image. The optical splitter has a light splitting effect, light emitted by the light-emitting device is shot outwards via the optical splitter, the image detection device collects light exiting from the optical splitter to form a detection image, and the image detection device processes the image and judges whether the optical splitter has a broken line defect, so that the detection is more reliable. The invention further provides an optical splitter detection method, which is intuitive in detection and high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a detection system and a detection method of a spectroscopic device. Background technique [0002] The imaging principle of stereoscopic image display technology is: based on the binocular parallax of the viewer, the left and right eyes of the viewer perceive the disparity map with image difference, and the viewer's brain forms a stereoscopic image based on the perceived image difference. [0003] Stereoscopic display parts are classified into glasses-type three-dimensional display parts and naked-eye three-dimensional display parts according to viewing forms. Among them, the glasses-type stereoscopic display unit requires the viewer to wear glasses to watch the stereoscopic image. Within the visible range of the glasses-type stereoscopic display unit, the viewer can move at will to see the stereoscopic image. However, in Viewing glasses-type stereoscopic display c...

Problems solved by technology

Due to the manufacturing process and other reasons, there is a broken line area in the light splitting device 1', and the broken line area will directly affect the display effect of the stereoscopic display device.

If the optical splitting device 1' is not detected for disconnection before assembly, it is directly installed on the display panel 2' and assembled into a three-dimensional display device. Moreover, the normal light-splitting device 1' cannot be replaced, resulting in the stereoscopic display device becoming a defective product. Therefore, it is necessary to detect the disconnection of the light-splitting device 1' before assembly.

[0005] The prior art discloses a cylindrical lens grating detection device, which includes a detection base, a traction support device and a transmission support device. The detection base is provided with a first main evaluation line perpendicular to the edge of the cylindrical lens grating to be detected. Refractive characteristics of the cylindrical lens grating. Observe the state of the evaluation line set under the cylindrical lens grating to evaluate the curvature and flaw of the lens edge of the cylindrical lens grating. This can only be confirmed when there is obvious bending or deformation somewhere in the evaluation line. There are defects in the area, and when the number of statistical defects on the unit area exceeds the quality control value, it can be determined that the cylindrical lens grating is a defective product, the operation is complicated, and the evaluation is based on the refraction effect of the cylindrical lens grating, there is a detection error, which affects Final test result
