Abstract

A system comprising an infrared radiation source, an infrared radiation sensor and means for generating and processing optical infrared signals, wherein the infrared radiation source is an electric lamp comprising a pass-band interference filter coating arranged on its inner or outer surface, which integrated pass-band interference filter coating, that is transmissive to infrared radiation in a wavelength range from 800 nm to 1200 nm, is useful for a wide variety of applications in detection, authentification, identification or remote control of objects, and is excellently suited for object detection under rough industrial conditions. Such a system provides a narrowband infrared signal in a specific frequency band that, in combination with a suitable sensor, reduces eavesdropping and is not sensitive to light sources, such as the sun and artificial light sources, that emit radiation in the visible and IR range of the electromagnetic spectrum.
