  • Patent number: 7733484
    Abstract: Embodiments of hyperspectral scene projection/generation systems and methods are disclosed. One method embodiment, among others, comprises dispersing a beam of light at one of a plurality of selectable wavelengths, the beam of light corresponding to a scene, and displaying a spectral image of the scene corresponding to the dispersed beam of light at one of the plurality of selectable wavelengths.

  • Patent number: 6485150
    Abstract: A tunable spectral source includes an enclosure having first and second apertures; an optical dispersive element positioned in the enclosure; and multiple pixel source elements that are individually controllable for selectively directing one or more broadband light signals through the first aperture to irradiate the optical dispersive element. Each of the broadband light signals irradiates the optical dispersive element at a unique angle of incidence. The optical dispersive element disperses the broadband light signals into spectral component signals at dispersion angles that are dependent upon the angle of incidence of each broadband light signal that irradiates the optical dispersive element. The portions of the spectral component signals that are emitted through the second aperture are determined by selecting one or more particular pixel source elements to irradiate the optical dispersive element.

  • Patent number: 5624437
    Abstract: A high speed, high resolution, programmable laser beam modulating apparatus includes a computer connected to a high resolution micromirror array having individually addressable and movable mirrors. The computer is also connected to a pulsed laser for controlling the emission thereof. A beam homogenizing optic changes an ablating input beam from the laser into a homogeneous beam having a uniform cross-sectional energy density. The mirrors are movable between an "on" position for reflecting a portion of the homogeneous beam onto a cornea, and an "off" position for reflecting the beam away from the cornea. The computer is programmed to move the mirrors to the "on" position in a series of predetermined patterns, and the remaining mirrors to the "off" position, and to fire the laser during the presence of each pattern, so that corresponding patterns of tissue on the cornea are successively ablated therefrom.
