Study of position-measurement of high-speed object based on laser technology

the system of position-measurement for high-speed moving object is introduced This system works with photoelectricity converting and can form a sensor wall having two coordinates in the sky: When the objection passes the sensor wall, some paralleling light is shutoff and light flux of receivers are changed, so the position of passing objection can be identified correspondingly. In this paper, the developing software-LabWindows/CVI and hardware equipments such as the form of laser screen, the choice of photosensitive elements are introduced In order to testing this system, an experiment is conducted Testing result shows that this laser measurement system is convenient to operate, and has high accuracy, good stability and quite safety.
