Partially coherent sources with radial coherence
Optics Letters, 2018 Partially coherent sources with radial coherence are proposed. They present a circularly symmetric intensity profile and a degree of coherence whose absolute value only depends on the angular difference between the two considered points. In particular, the source is completely coherent at pairs of points belonging to the same radius.

Average coherence approximation for partially coherent optical systems [PDF]
, 1996 We introduce an approximation to the Hopkins integral for partially coherent optical systems. The average coherence approximation yields results close to the Hopkins integral for a wide range of coherent transfer functions and illumination functions and ...

Interferometric electro-optical signal processors with partially coherent illumination [PDF]
, 1992 Fourier- and Hartley-related transforms are realized in a family of interferometers. The implementation of these interferometers as image correlators is investigated theoretically and experimentally with both coherent and spatially incoherent ...

Partially Coherent Channel Estimation Algorithm based on IR
Guangtongxin yanjiu, 2021 For millimeter-wave large-scale Multiple-Input Multiple-Output (MIMO) systems with hybrid precoding, due to the hardware defects in the system, random phase shifts will be introduced in the received pilots, which will make the performance of traditional ...
