Patent ID: 8269881

Claim:
An imaging apparatus comprising: a spatial light modulator configured to receive coherent incident light representing an incident light image, to modulate said incident light to form spatially modulated light, and to attenuate said coherent incident light, wherein the image apparatus is configured to determine an intensity for a portion of said coherent incident light that comprises a detected intensity value and an attenuation value corresponding to said portion of said coherent incident light; and an image capture device located in a Fourier plane of said spatially modulated light and configured to receive and capture said spatially modulated light, the image capture device comprising at least one detector configured to sample the spatially modulated light and detect the intensity value; wherein feedback is sent to said spatial light modulator to cause said spatial light modulator to form, using one or more attenuation values and on a pixel by pixel basis, a uniform output image comprising spatially modulated light with a maximum uniform intensity distribution.
