  • Patent number: 8965193
    Abstract: Systems and methods are provided for a solid filled mirrored lens system capable of wider fields of view and wider spectra than current lens systems. The mirrored lens is used to focus light incident upon a right circular cylindrical central body comprising a substantially planar first surface and a substantially planar second surface. A primary reflecting surface is located on the second surface of the central body and shaped as an annulus with a void in the central region of the second surface. Further, a secondary reflecting surface is located in a central region of the first surface facing the primary reflecting surface.

  • Patent number: 7146060
    Abstract: A phase distortion device/method has been developed to improve images. A wave source generates waves, which stimulate the reflection and/or emission of narrow-band waves from an object of interest or a nearby object. The phase distortion of the narrow-band waves is used to obtain an impulse response function, which is then used to correct an image formed by illumination waves.

  • Patent number: 6876483
    Abstract: Apparatus which directs light rays from a distant target area scene to a plurality of wavelength detection systems without wavelength degradation. A reflective afocal telescope directs the light rays from the scene to a MEMS mirror array which redirects the rays to selected ones of the detection systems. The MEMS mirror array has individually controllable mirror elements which are driven to predetermined angular orientations to accomplish the light ray redirection. Outputs from the detection systems may be provide to a computer for analysis and/or viewing.
