Abstract
The invention relates to an appliance for detecting objects in a detection region, with a radiation device for emitting an electromagnetic scanning beam into at least a part of the detection region and with a device for modulating the scanning beam as well as with a detection device for the detection of reflected radiation from at least a part of the detection region and with a device for evaluating the time response of the detected, reflected radiation, in dependence on the modulation of the scanning beam. According to the invention, one can envisage the radiation device comprising a radiation source radiating a diffusion device scattering the radiation at least partly into the detection region, in order to be able to apply an as powerful as possible laser as a t source without endangering the eye safety or the general safety of persons.
