Abstract
The invention relates to a high-light-reflection-surface coaxial optical path detection system based on refraction imaging. The high-light-reflection-surface coaxial optical path detection system based on the refraction imaging comprises an imaging device and an image controller connected with the imaging device; one side of the imaging device is fixedly provided with a light source generating device; a prism is vertically arranged below a light inlet of the imaging device; light rays emitted by the light source generating device are firstly subjected to diffuse reflection by the surface of a to-be-detected plate, then are refracted by the prism, and enter the imaging device; the imaging device transmits formed images to the image controller; the image controller processes the received images so as to obtain high-definition high-light-reflection plate surface detection images. The detection system achieves a coaxial optical path detection effect by adopting a refraction optical path; diffuse reflection light beams are adopted in the refraction imaging; the high-light refraction phenomenon caused by that mirror surface reflection light enters the imaging device directly; laser is adopted as an illumination light source, the chromatic dispersion phenomenon caused by the refraction imaging of the prism is prevented; the imaging clearness is ensured; the high-definition high-light-reflection plate surface detection images are obtained.
