Beschreibung
Zusammenfassung:	A device for radiation detection over a broad field, especially for laser radiation detection. The device comprises a photodetector associated with an optical receiver formed by two diaphragms which delimit the field, and an optical diffusing element. In a preferred embodiment, a diffusing paint is deposited on a flat surface of a mechanical part, and a mirror for reflecting the diffused radiation makes it possible to mount at the rear end of the device either the photodetector or an optical fiber terminal to which the photodetector is remotely coupled.
