Abstract
This thesis focuses on the photoelectric testing technology，especially the technology on the characteristic symbol of linear CCD on the base of deep discussing on the structure and principle of CCD、the signal processing and the application of the photoelectric sensor. This design which is the application of modern photoelectric testing technology is the measuring instrument on synthesizing of the acousto-optic effect and the image sensor. The fundamental and applied research on the characteristic symbol photoelectric testing technology is certainly on the leading edge of the discipline because that it is hard for traditional photoelectric testing technology to satisfy the testing request. Simultaneously，it also has the important and widespread practical application prospect. This measuring instrument mainly includes several parts： 1、Semiconductor laser generator，2、ultrasonic generator， 3、linear CCD，4、electric circuit parts，5、data acquisition system ，6、computer system. The laser which produced by the Semiconductor laser generator creates diffraction after receiving the supersonic wave disturbance in the medium. The diffraction light transforms to the electrical signal by entering the linear CCD. The electrical signal enters in the monolithic integrated circuit after enlargement processing and transforming by the A/D transformation component. Finally，the signal inputs to the computer system through USB100 for data processing.
