ANGULAR SEPARATION AND SPECTRA OF 2 POINT SOURCES DETERMINED FROM MEASURED SPECTRAL COHERENCE

The theoretical foundation is described not only of bow to determine t he angular separation of two point spectral sources, but also on how t o recover each spectral profile from the measured complex degree of sp ectral coherence. It is shown that the so-called space-frequency equiv alence law is not always required. A simple simulation experiment is d one by incorporating paired superluminescent diodes as the two point s ources with different broadband spectra. The experimental results veri fy the validity of the theoretical prediction.
