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.
