摘要

In this paper, an automatic vision system based on optical scanning mechanism is developed for solar cell wafer. It consists of optical scanning mechanism with near-infrared(NIR) camera optics, machinery and control system, algorithm of defect detection and software. Optical scanning mechanism is composed of geometrical camera optics and structured hybrid illumination system(SHIS). It is used to inspection of surface defects. Also, NIR camera optics is used for inspection of defects inside solar cell wafer. It is shown that the automatic inspection system give satisfactory performance for micro defects in solar cell wafer.
