Abstract :
A real-time sectional image measuring system is developed using the time-sequentially-coded grating method, and its application to automatic 3D image data measuring systems is studied. A PLZT electron shutter array is used to project time-sequentially-coded grating patterns on the object. The sectional image is calculated from deformed grating images which are picked up by a TV camera. This system takes about 530 ms to project the 100-slit time-sequentially-coded grating patterns and about 30 ms to calculate one sectional image
