Coherent optical processing methods have been investigated for the real-time recognition and control of mass-produced pieces in automatic machining and assembling lines. In particular, an optical correlator is proposed in which the information of a master piece is stored in a hologram. Problems such as the optimization and generation of the hologram, the detection of particular defects, the adaptation of the response curve to the practically given tolerances, and the reliability have been investigated, and prototypes of control systems have been realized.
