As a photoelectric sensor, the CCD camera which is composed of solid state elements, is small in size and light in weight. It not only has advantages of a low operating voltage, good reliability and long service life, but also facilitates picture dot addressing. Therefore the CCD camera has been used more and more widely in the sphere metering instrument test, production process monitoring and quality control in industry. This detecting system is made up of a CCD camera and a monolithic microcomputer. The following is the operating principle of the detecting system in detection of the match of light axis and electric axis and the transient performance of antenna tracking system of radar.
