Abstract: An optical monitoring system has been developed by the authors aiming at real-time monitoring of laser cutting of thick plates of mild steel. This optical system uses photodiodes and a NIR camera as sensors. The concepts and results of the photodiode-based monitoring system have already been reported [1,2]. This paper is dedicated to the development of the optical set-up for camera-based monitoring of the laser cutting process. Firstly, some general aspects concerning the sensing principles and the conceptual …
