Abstract
An imaging system is provided with integrated measurement of wear in at least one of the system's optical elements working in the transmission mode, in a given spectral band. The system includes a combination of optical elements and an imaging detector on which there is projected the image of an observed scene by means of the optical elements which produces a video signal of the observed scene. An alarm is provided to signal the existence of an optical element having a degree of wear which exceeds a critical value.
