摘要

Abstract: An optical measuring system with high precision, high speed, and a simple configuration is introduced. The surface profile of a 3-D diffuse object is obtained by measuring the phase of the intensity distribution deformed by the surface. The phase-shifting technique is performed with an electro-optic modulator, with a CCD used to detect the distorted images and a 286AT computer to process the data. The experimental result of a mannequin head is presented, which shows that a range up to 10 cm and a resolution better than 0.065 mm are available. !7
