International Conference on Advanced Phase Measurement in Optics and Imaging
This paper presents a method for discontinuous surface measurement by using only four fringe images. The technique has the advantage of measurement speed over conventional methods with similar capabilities that rely on utilizing at least nine fringe images. Simulation results demonstrated that the technique can be used to effectively measure steep height variations in an object as well as discontinuous surfaces.
