光源

A measuring system which mainly consists of a high precision motorized translation stage of one dimension, POINT GREY Flea2-14S3 CCD camera and LED light source was designed and constructed. Based on a detailed analysis for experiment results, the periodic changing law of system error of LED facula centroid location in this measuring system was found. The results indicate that based on Flea2-14S3 CCD camera, the random error of facula centroid location is about 0.018 pixels, the system error is about 0.06 pixels, and the total error is about 0.063 pixels (1/15 pixels).
