Incoherent Multiple Aperture Optical Imaging Systems: Analysis and Design.

Abstract

Various multiple aperture optical arrays were compared while imaging objects illuminated with incoherent light. The aperture arrays contained from one to four sub-apertures. The objects were edges, slits, rectangles and circles. An emphasis was placed on edge resolution, and the author derived his own set of resolution criteria. Based on this analysis, a tight square four-element array was the best performer. The study concluded with an analysis of design criteria for optimum incoherent imaging resolution. Max sub-aperture size, min sub-aperture spacing, max number of sub-aperture elements, and a symmetric pattern were all determined to be desirable in order to obtain the best performance.
