Patent

CA 2391782

An optical system for viewing hot objects (2) is disclosed. The system projects electromagnetic radiation (26) to the part surface and detects the reflected portion. Based on wavelength and/or modulation of the applied illumination, the surface characteristics of the part can be observed (30) without interference from self-emitted radiation.

L'invention concerne un système optique de visualisation d'objets chauds (2). Le système projette un rayonnement électromagnétique (26) sur la surface de la pièce et détecte la partie réfléchie. Sur la base de la longueur d'onde et/ou de la modulation de l'illumination appliquée, les caractéristiques de surface de la pièce peuvent être observées (30) sans parasite provenant du rayonnement auto-émis.
