要約(英語): 3D shape measurement systems that use contactless methods are required for quality inspection of metal molds and electronic parts in industrial fields. A fringe projection method with phase-shifting method offers the advantages of high precision and high speed. Recently, since the size of electronic parts has become smaller, the pitch of a grating pattern projected onto a specimen should also become smaller. In this paper, a small pitch fringe projection method using Talbot effect with an SLD (Super luminescent diode) and a method to incline the appearing area of the fringe pattern are proposed. A linear fiber array with four cores is prototyped. A phase-shifting method using the linear fiber array is also proposed. The effectiveness is confirmed with the experimental results of shape measurement using a 3D shape measurement setup built with proposed method.
