Sažetak
Reticle trackers have been used successfully with a beam splitter for tracking and discrimination of several moving incoherent (heat) optical sources in the mathematical framework called Independent Component Analyses (ICA). Here we further explore the theoretical basis of the coherent and partially coherent illumination by laser for the possibility of blind source de-mixing. An application of the partial coherence theory, the Huygens-Fresnel principle is utilized to formulate the problem. When incoherence is assumed a linear ICA model is obtained while in most general case of either partially or totally coherent optical radiation the resulting signal model is inherently nonlinear. Since the incoherent limit in linear ICA, as published early, we wish to call attention to the fact that this partial incoherence to fully coherent cases might be a test bed to attempt to solve nonlinear ICA problem by perturbation methodology. For example, it can be transformed into linear one under very special condition that assumes no relative motion between the radiating sources. In the most general case of either partially or totally coherent radiation tracking of the several moving optical sources by using the beam splitter based reticle trackers becomes intractable.
