Applied study of the timely detection for the variable figure area using laser optical fiber system

A laser optical fiber system of detecting the variable figure area with CCD was presented, and the optic imaging and computer processing techniques adopted in this system were described. This system can calculate quickly and simultaneously the figure boundary locus surrounding area recorded by CCD which comes into being gradually, realizing the simultaneous indications of imagery and its area. This system has the advantages such as good real-time ability, high automation and high measuring accuracy.
