Abstract

Object detection system that makes it possible to with extreme safety read a holed barcode tag in the surface treatment process of an automotive factory, and/or to reliably detect, classify and/or decode other moving objects such as a moving machine for operator safety, to classify a moving vehicle at a driving gate or truck scale for access control or debiting, and to record the direction, speed and length of a moving railcar for improved logistics control. The system comprising least one illumination unit with at least one light emitting diode with a focusing lens that transmits amplitude modulated and preferably infrared light of 700 - 1200 nm wavelength in direction to a barcode tag or other object to be detected, and, where at the other side of the barcode tag or other object a reader is located, said reader comprising a photo detector that is especially sensitive for light of the wavelength and modulation pattern that is sent out from the illumination unit.
