Abstract
A focal plane detector adapted to be calibrated using an image of part of the human body. Further, a method of calibrating a focal plane detector having a plurality of detector elements, comprising the steps of presenting a first and a second image to the focal plane detector array, measuring the output from each detector during each first and second image, analysing the outputs and compensating for errors in the output of each detector element such that the outputs from the detector elements are substantially equal when illuminated with electromagnetic radiation of a given intensity. The first and second images have substantially no discernible features therein, and one of the first and second images comprises an image of part of the human body. The apparatus and method are particularly applicable to focal plane detectors sensitive to infrared radiation.
