Abstract
An optical detection system for forming an image of a field of view in an object plane onto an image plane in which the electromagnetic radiation image is transmitted to a detector array at the image plane via an optical distorting element such as a reflector 11, so as to impose a non linear relationship between areas in the image and object planes.
Claims9
An optical detection system comprising a two dimensional array of regularly spaced detector elements and optical means for forming an image of a field of view in an object plane onto an image plane at which the array is located, the optical means being arranged to map a designated area of the object plane onto the array and including a distorting optical element which imposes a non-linear relationship between areas of the object plane and areas of the image plane.
