Most optical topology systems use a single wavelength laser for projection, using a swept spot, a moving line, or a projected grating. In a typical projected grating system, the gratings are shifted and a series of images are used to recover the 3D s

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 have developed a method of creating arbitrary moire patterns from any arbitrary diffusely reflecting object that does not require any physical grating fabrication. The moire patterns can be made in any form, from equal depth contours, to error map

Experiments using Liquid Crystal Televisions (LCTVs) as spatial light modulators for optical correlators, and optical input devices, have been reported upon widely. Moreover, applications of these devices for target recognition and automatic inspecti

Several methods for generation of three dimensional surface shapes from variable resolution video moire contours are described. In a classical moire system, a physical grating is projected on a target and also used to view the target. The moire conto

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
