Integrated imaging with a centrally obscured logarithmic asphere

We study an integrated computational imaging system which incorporates a centrally obscured logarithmic asphere lens and rapid maximum entropy processing. A careful study of imaging for a two-point object at various distances is presented to demonstrate diffraction limited resolution and a tenfold increase in the depth of field. Also the overall transfer function is defined and measured. This system is well suited to high-quality photography where one requires excellent resolution and good contrast with little or no artifacts.
