Abstract

A study of imaging in an isoplanatic optical setup with a spatially incoherent illumination is presented. In such optical setups a light intensity distribution in an image plane can be calculated by a convolution of an input field with a Point Spread Function (PSF). Additionally a numerical simulation of incoherent monochromatic illumination is done by an integration of intensity images obtained with different random initial phase distributions (equivalent to a long exposure with a rotating diffuser in an optical setup). When an optical system is non space-invariant the point source image changes in various regions of the image plane and imaging simulation becomes complicated. Method with a simple convolution with PSF distribution cannot be applied because there is no one well defined PSF for the whole optical setup. This second method needs a bigger computational effort but can provide imaging modelling for both isoplanatic and non space invariant situations. In this contribution we compare the two mentioned methods in terms of imaging quality and its agreement with theoretical expectations. We give some statistical analysis of a contrast and noise level of the obtained pictures. We discuss the advantages and limitations of both modelling techniques for typical greyscale test patterns.
