Apparatus and method for capturing still images and video using diffraction coded imaging techniques
First Claim
1. An apparatus for precompensating for the effects of diffraction and wave-optical interference comprising:
- a sensor;
a physical aperture pattern constructed to emulate a result of a desired aperture pattern if the desired aperture pattern did not produce wave-optical interference and diffraction effects,the physical aperture pattern to receive radiation from a scene within the visible spectrum and pre-compensate for the wave-optical interference and diffraction effects of the desired aperture pattern, taking advantage of wave-optical interference and diffraction effects of the physical aperture pattern to project a radiation pattern, the radiation pattern projected in a desired overlapping pattern that would have resulted if the physical aperture pattern had the desired aperture pattern but without the wave-optical interference and diffraction effects.

Abstract
An apparatus and method are described for capturing images in visible light as well as other radiation wavelengths. In one embodiment, the apparatus comprises: a diffraction coded imaging system including a plurality of apertures arranged in a diffraction coded array pattern with opaque material blocking array elements not containing apertures; and a light- or radiation-sensitive sensor coupled to the diffraction coded imaging system array and positioned at a specified distance behind the diffraction coded imaging system array, the radiation-sensitive sensor configured to sense light or radiation transmitted and diffracted through the apertures in the diffraction coded imaging system array.
