Light pattern projector especially for welding

摘要: Structured light patterns are introduced into the arc vicinity within field of view integral optical sensor on a gas tungsten welding torch. Processing image yields data needed to guide torch and control assess weld process. The has projector system with remote source flexible fiber optic bundle over which pattern passes an exit projection relay assembly mounted A programmable laser projector, useful for other applications, beam deflection device that traces two-dimensional entrance coherent bundle; no moving parts or electrical connections at terminal end. An optional modulator changes intensity spatially temporally.
