Abstract

An optical sensor head for the directional detecting of optical radiation has an arrangement of individual optical systems that are differently sloped with their optical axes, are convergently aligned in the viewing direction and each have conical, partially overlapping viewing areas. To provide an exact bounding of the observation sector assigned to the sensor head without any impairment of the operatability, at least one outer-edge-side individual optical system of the sensor head is provided with a beam diaphragm which partially shades the assigned viewing cone. At least one of the neighboring optical systems, which is situated closer to a sensor center, is arranged with its light entrance opening approximately at the level of the diaphragm-bounded edge beams of the outer-edge-side individual optical system.
