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.
Claims18
A hyperspectral scene generation system, comprising:
- an image generator for generating broad band light images of scenes from memory;
- a tunable dispersive device configured to disperse a beam of light from the image generator at one of a plurality of wavelengths, the beam of light corresponding to a scene;
- and
- a display system configured to display a spectral image of a scene corresponding to the dispersed beam of light at one of the plurality of selectable wavelengths;
- and
- a focusing element adjacent to the display system and a filter disposed between the dispersive device and the focusing element, the filter positioned to enable the dispersed beam corresponding to the spectral image of the scene at one of the plurality of selectable wavelengths to pass through to the focusing element and block out undesired dispersed beams of light corresponding to the scene corresponding to undesired wavelengths.
A hyperspectral scene generation system for converting substantially broadband images into selectable spectral images, comprising:
- means for storing broadband images of scenes in memory;
- means for dispersing an incident beam of light at one of a plurality of selectable wavelengths, the incident beam of light corresponding to a scene generated from memory, the dispersed beam of light corresponding to a spectral image of a scene;
- and
- means for displaying the spectral image of the scene at one of the plurality of selectable wavelengths;
- and
- means for filtering the dispersed beam of light and means for directing the dispersed and filtered beam of light.
A hyperspectral scene generation system comprising:
- means for generating a light beam corresponding to a scene at a plurality of wavelengths;
- first means for filtering the light beam;
- means for electronically selecting at least one wavelength band corresponding to a spectral image of a scene from a plurality of selectable wavelengths;
- means for directing the filtered light beam to the means for electronically selecting at least one wavelength band;
- second means for filtering the at least one selected wavelength band of light;
- means for directing the at least one selected wavelength band of light;
- and
- means for displaying the spectral image of the scene.
