Abstract:The paper aimed at optical axis parallelism detection problem of the key opto-electrical system parts,the opti-cal spot image collection and detection data analysis were down,also the image collection and handling hardware system based on CCD and USB image capture card were built,through computer driving CCD,optical spot image collection was fin-ished and the optical spot it gotten was handled to get coordinate figure of optical spot in target plane.By means of digital image management to get centroid coordinates in the target plane.According to the optical imaging principle,the optical parts of the laser optical axis deviation angle value was calculated,opto-electrical system optical axis parallelism adjustment value was gotten,it provided the tool about optical axis parallelism detection of the key opto-electrical parts and the data a-nalysis.
Keywords:optical axis parallelism   image processing   optical spot measurement
