Abstract
Features of spatial filtering of partially coherent images are investigated. A radiooptical analogy method for analysis of optical system operation is used. Analytic expression of optical transfer function for arbitrary coherence of illumination field, for arbitrary aperture factors and for arbitrary defocusing parameter is deduced and investigated by numerical methods. Efficiency of spatial filtering of partially coherent images has been showed by laboratory experimental system using illumination source with variable coherence. An original method with two synchronously tunable moire patterns has been used for optical transfer function measurements. Investigation results are interpreted from the point of view of solving inverse problem.
