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.

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 and precompensate 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.
