Radiation detector
First Claim
1. A radiation detector for simultaneously detecting electromagnetic radiation from a number of separate receiving regions, comprising a single radiation receiver common to said number of separate receiving regions, a plurality of optical bundling means, each one of said optical bundling means being operatively related to a given one of said separate receiving regions and being arranged such that the radiation emanating from the individual receiving regions is transmitted to the single radiation receiver, each of the optical bundling means comprising an aspherical surface having two different main radii of curvature, and the radiation receiver is arranged at least approximately at one of the main focal points of the individual surfaces, for generating a pattern of spaced apart substantially strip-like receiving regions, each having a lengthwise extent considerably exceeding the width thereof.

Abstract
A radiation detector for simultaneously detecting electromagnetic radiation from a number of separate receiving regions by means of a single radiation receiver. Optical bundling means are arranged such that they direct the radiation emanating from the individual receiving regions onto the single radiation receiver. The optical bundling means comprise surfaces having two different main radii of curvature. The radiation receiver is arranged at the one main focal point of the individual surfaces.
