ABSTRACT:
Processing of the two-dimensional image of a three-dimensional object, such as the human cornea, that has been illuminated with a structured light pattern. A specially filtered Fourier transform and inverse transform are processed to yield the instantaneous spatial frequencies of the illuminated pattern. The instantaneous spatial frequencies are mapped to the instantaneous dioptric powers or depth coordinates of the object's surface.
