Appl. No.:

12/943651

Inventors:

James A. Fry - Orlando FL, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

F41G 7/22
G06K 9/20

G06K 9/00

US Classification:

244 316, 244 31, 244 315, 244 319, 342 52, 342 53, 342 61, 342 62, 382100, 382103, 382106, 382107

Abstract:

A vehicle including electro-optic (EO) imaging has a vehicle body having an outer surface including a front portion and a side portion, wherein the side portion includes a plurality of portholes. A propulsion source is within the vehicle body for moving the vehicle. A fixed EO imaging system having a field-of-regard (FOR) includes a plurality of fixed EO imaging sub-systems arrayed within the vehicle body. The fixed EO imaging sub-systems each have a different field-of-view (FOV) for providing a portion of the FOR and include a camera affixed within the vehicle body and an optical window secured to one of the portholes for transmitting electromagnetic radiation received from one of the portions of the FOR to the camera, wherein the cameras each generate image data representing one of the portions of the FOR therefrom. A processor is coupled to receive the image data from the plurality of fixed EO imaging sub-systems for combining the image data to provide composite image data spanning the FOR.

Abstract:

A vehicle including a scanning imaging system includes a vehicle body having an outer surface, a propulsion source, and an optical window secured to the outer surface of the vehicle positioned on an optical axis for transmitting electromagnetic radiation received from a portion of an area of interest to the scanning imaging system. The scanning imaging system includes a first achromatic prism pair having prisms with different materials that have different refractive properties, and a second achromatic prism pair having prisms with different materials that have different refractive properties, both positioned on the optical axis. A camera fixed in location is optically coupled to form images from the electromagnetic radiation after being bent by the achromatic prism pairs. A motor including a controller independently rotates the first and second achromatic prism pairs about the optical axis for scanning within the area of interest.
