Radiometry and Coherence

Inverse problems and coherence

“…In contrast to the situation of the generalized Van Cittert-Zernike theorem (where I < a), the source coherence cannot be uniquely determined from the far-zone intensity distribution only, when I and a are of comparable magnitude, unless a is known a priori (see, e.g., [9]). With respect to the problem 5) we mention the interpretation o f the farzone intensity distribution in terms of a modem version of…”

The importance of coherence in inverse problems in optics

“…Comprehensive reviews of the various aspects of the deterministic inverse problems are available [Ferwerda, 1978;Hoenders, 1978;Schrnidt-Weinrnar, 1978;Ross et al, 1980;Boerner, 1980]. Of more recent interest are the corresponding inverse problems for partially coherent sources or stochastic scatterers (such as fluctuating continua, random distributions of discrete scatterers, or rough surfaces) characterized by correlation functions or statistical distributions rather than by deterministic field amplitudes [Ferwerda, 1978;Ross et al, 1980;Baltes et al, 1978;Jakernan and Pusey, 1980;Selloni, 1980;Goulard and Emrnerman, 1980]. SUMMARY The various inverse problems of statistical optics can be categorized as follows.…”
