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.
