Paper Abstract

Based on crystal optics, Conoscopy is a unique implementation of polarized light interference process,. In the basic interference set-up a light beam is projected onto a diffusive object. The beam creates a light point on a target, which via reflection disperses the light in all directions. A complete solid angle of the diffused light is analyzed.. The measurement process corresponds to the retrieval of a distance of the light point from a fmed reference plane. Three dimensional measurement systems based on Conoscopic Holography are steadily gaining ground against conventional techniques. Conoscopic system have evolved from an exotic solution to the fist choice for all measurement problems not covered by triangulation techniques. Currently, they can be utilized on many applications such as quality control measurements, digitizing, reverse engineering and in-process inspection. A review of Conoscopic Holography principle will be presented in the first part of the paper. The exclusivity of Conoscopic Holography and its distinction from commonly used techniques will be reviewed.
