Blind separation of optical tracker responses into independent components discriminates optical sources

An optical system based on rotating reticle is used to determine polar co-ordinates of the primarily infrared optical source. Such system fails to discriminate simultaneously several optical sources. We demonstrate experimentally in a case of two optical sources that this drawback can principally be overcome by application of the blind signal separation (BSS) algorithms on data recorded at the outputs of an originally modified optical system. Separation of modified optical system responses into independent components yields modulating functions that carry information about polar co-ordinates of the corresponding single optical sources.
