| Abstract: | his paper describes the principle and the method of a new-type auto focussing system. After the optical signals are transferred by CCD and the controlling and processing are completed by single chip computer, the auto-focussing of the optical system is achieved based on the patterns of laser wave interference frings. The system has the advantages of high precision, high speed and wide use. |
