Imaging with Sources of Non-uniform Distribution

This paper deals with the problem of microscopic image formation using sources of non-uniform distribution. In the case of partially coherent imagery the source distribution plays a significant role in the final image quality. The question is here discussed from the point of effective transfer function of the system and also from two-point resolution. Some interesting results are obtained and it is suggested that, depending upon the object structure, different source distribution might be optimized with respect to different image assessing criteria, e.g. effective transfer function or two-point resolution.
