Abstract

The characteristic and work principium of Charge Coupled Devices (CCD) is expatiated. Based on CCD measuring technology, a geometric objects photoelectric comprehensive measuring system is described in the paper, which is applied to measure the thickness of quartz tube wall non-contacted automatically with a line CCD device. The system is composed of a semiconductor laser source, a main fine mechanic system and controller, a real-time controlling system with SCM and data processing system by PC. The optics system, CCD hardware circuit and SCM control system are mainly discussed in this system. The system work process: optics, machine, electron and computer are organically combined, the line CCD in this instrument can measure the distance between two laser beams which are reflected from the outside and inside surfaces of quartz tube wall. Comparisons between the system and traditional measurement instrument are provided with: high measurement precision and efficiency; celerity and real time. In addition, applications of the system are viewed in the geometric objects foot-line real-time detection of the tube wall thickness and plank thickness, and medicine and liquor manufacturing, and the system error is analyzed.
