COLOR SENSING FOR LASER DECOATING

摘要

A coating removal apparatus utilizing a common optics path to provide laser pulses to a coated surface and to direct a light illumination reflected from the coated surface to a photosensitive detector and analyzer. The apparatus is an integrated device including a laser source, a beam splitter, scanning optics, a waste removal apparatus, one or more light illuminators, a photosensitive detector, a comparator, and a control logic circuit. Alternatively, the laser source is external to the integrated device and a fiber optic cable is used to connect the laser source to the integrated device.
