| Abstract: | This paper describes the principle and the feasibility of two dimensional digital autocollimator in which a area-array CCD image sensor is used. High-speed data acquisition andprocessing hardware and software under microcomputer control were designed.The correctmemorization of window image,point-source centre defination using subdivision methodswith subpixel accuracy were realized.Finally test result was given. |
