Abstract:
1. A method for temperature compensating a focal plane array having a plurality of pixel locations comprising the steps of: measuring the temperature of said focal plane array; converting said measured temperature of said focal plane array to an address; addressing at least one memory location in which operating parameters of each pixel location are stored; reading out said operating parameters for an addressed pixel location from said at least one memory location; applying said operating parameters to said pixel location to effect changes in pixel operating characteristics; measuring radiant energy incident on said addressed pixel location; processing said operating parameters of each pixel location from said at least one memory location with said measured radiant energy incident on said addressed pixel location to provide a temperature compensated measurement; and repeating the steps of measuring radiant energy and of processing said operating parameters to provide a temperature compensated measurement for each pixel location in said focal plane array.
