Paper Abstract

The principle and the firstresults of a new 3D camera will be presented. This camera is based on a holographic technique named conoscopic holography. The simplicity of the technique, using only a crystal, waves plates and polarizers, and its compatibility with CCD sensors make possible the fabrication of low cost and flexible conoscopic vision systems. The first prototype is an tive rangefmder which will be developed into a profilometer and a 3D camera a resolution of 1 jnn and a precision of a 2-3 jim have already been obtained. The numerical processing is based on Fourier Transforms, quickly performed by available dedicied hardware.
