Analysis and Design Tools for Passive Ranging and Reduced-Depth-of-Field Imaging
Abstract
The imaging systems considered in this research involved optical image acquisition and digital signal processing. The work early during the period of this grant centered on a technique that is analogous to range detection in radar. This work used design tools in the spatial frequency domain, and the validity of the approach was confirmed in both simulations and experiments. Other work concentrated on design of the point spread function. An information theory approach was used, and the orthogonality of the images was considered. This work led to special forms of structured illumination that can be used to reduce the depth of field of an imaging system. An indirect, but important, result of the research during this period was an impact on the growth of the interest in the field of hybrid optical/digital imaging systems, or "integrated computational imaging systems" or "wavefront coding" as it is also called.
