Abstract:
1. Image processing apparatus comprising: (a) modulation means for modulating an input image passing through a medium and applying the resulting broad non-focused modulated aberrated image signal emerging from the modulation means to a high pass optical filtering means for removing a DC light component to reduce quantum noise and thus improve detection of small image features; (b) image magnification means for magnifying said broad non-focused modulated aberrated image signal emerging from said high pass optical filtering means to produce a magnified aberrated image signal; (c) a two-dimensional image demultiplexer means for detecting said magnified aberrated image signal; (d) calculating means coupled to said two-dimensional image demultiplexer means for calculating separate phase image signals and amplitude image signals; (e) mixing means for mixing the separate phase image signals and amplitude image signals; and (f) display means coupled to an output of said mixing means for displaying images having both phase and amplitude information.
