Abstract: This paper describes the use of optical fringe projection method for 3-D surface profile measurement of object. In this method, sinusoidal linear fringes are projected on the object surface by a programmable liquid crystal display (LCD) projector. The image of the fringe pattern is captured by a CCD camera and processed by phase-shifting techniques. A simple procedure is described which enables calibration of the optical set-up for subsequent quantitative measurement of unknown object shapes. This method is relatively simple and accurate, and is capable of conducting fully automated measurements.
