A variable resolution video machine vision system has been built which will determine the 3-D shape of a firing pin from the dent it has made in the primer of a shell. The system can also compare primer dents in different shells and determine if a 3-

A variable resolution video machine vision systems has been built which generates twice the number of depth contours for a given grating spacing as a conventional moire system. This variable resolution system uses a Mach-Zender interferometer to proj

We demonstrate a hybrid electronic-optical real-time system that performs 3-D face recognition. We constructed custom reference gratings that formed a desired moire´ pattern when mixed with images of structurally illuminated faces. The moire´ patte
