Optical wide angle sensor head
First Claim
1. An optical wide angle sensor head for directionally sensing optical radiation, comprising housing means for mounting said sensor head, a plurality of individual optical elements (11) for said sensing, each optical element having its own light entrance and field of view and its individual optical axis, and means for mounting said individual optical elements in said housing means in such positions, that said individual optical axes converge in an intersection (11b) forming an origin of a three-dimensional coordinate system as a reference system of said wide angle sensor head, said intersection (11b) being located upstream of said light entrances as viewed in a direction of incident light entering said light entrances.

Abstract
An optical wide angle sensor head for directionally sensing optical radiation is made of a plurality of individual sensor optical elements. Each sensor optical element is arranged at an input end of its own fiber optical conductor and has its own light entrance, its own field of view and its own individual optical axis. Neighboring fields of view may overlap each other. The fiber optical conductors lead to a transducer for converting the individual light signals into respective electrical signals. The individual sensor optical elements are arranged on a common mounting member in a housing so that the individual optical axes pass through a common intersection in front of said light entrances. The mounting member is a flat plate or a concave plate having a concave curvature facing in the viewing direction, whereby a spherical mounting is avoided.
