Device for detection and localization of laser radiation sources

Means for detection and localization of laser radiation sources, disposed in the image field of an imaging optical radiation-sensitive detector and an electronic signal processing connected to the detector, wherein between the laser radiation source and the optical system (2) as the cross grating (3) formed diffraction grating is arranged such that the diffraction orders of the cross grid (3) which is designed as planar array detector detector (1) in the focal plane of the optics (2) are imaged and the detector (1) connected to the electronic signal processing is configured such that between punctiform and line-shaped light emitting points of the diffraction orders can be distinguished.
