ABSTRACT:
A detector device for the directionalized detection of laser radiation has a plurality of individual optics, which together can measure radiation throughout a defined total angle of detection. Each individual optical system comprises a fiber optic guide with a corresponding light concentrator, which has a generally funnel-shaped, dynamically balanced design, tapered towards the end of the fiber optic guide. The funnel wall reflects inwardly and is shaped, so that the following condition is fulfilled:
