Recently, authors were proposed a small pitch fringe projection method using Talbot effect with an SLD (super luminescent diode) with inclining the appearing area of the fringe pattern. The phase of the projected fringe is shifted using a linear fiber array with four cores. In this paper, an application of these methods to height measurement of BGA (ball grid array) is performed.
