Abstract
A relation between spatial coherence and source encoding intensity distribution is presented. Since the spatial coherence requirement is determined by the signal processing operation, a strict coherence source may not be needed for the processing. The advantage of the source encoding is to relax the constraints of strict spatial coherence requirement so that the signal processing operation can be carried out with an extended incoherent source. The effects of signal sampling on coherence requirement is discussed. The advantage of signal sampling is to improve the degree of temporal coherence in the Fourier plane so that the signal can be processed in complex amplitude with a broadband white-light source. Finally, experimental demonstrations are included.
