Assignee:

Raytheon Company - Waltham MA

International Classification:

H04N 7/18

US Classification:

348144, 348E07085

Abstract:

Embodiments of a rolling-shutter imaging system with synchronized scanning illumination and methods for higher-resolution imaging are generally described herein. In some embodiments, the imaging system includes a focal plane array (FPA) and a read-out integrated circuit (ROIC) configured to activate only a portion of the FPA during an integration time. The imaging system also includes a scanner synchronized with the ROIC to illuminate only a portion of a sensor field-of-view (FOV) of the FPA within a scene that corresponds to at least the activated portion of the FPA. The imaging system may also include beamforming optics to generate a beam of light to illuminate the portion of the sensor FOV corresponding to portion of the FPA that is activated.

Abstract:

An optical switching assembly having an optical path therethrough includes an optical element, a base frame, an optical support that supports the optical element and is pivotably mounted to the base frame, and a linkage. The linkage interconnects the base frame and the optical support to effect movement of the optical support between an aligned position where the optical element is in the optical path and a non-aligned position removed from the aligned position. The linkage has two over-center positions that respectively correspond to the aligned position and the non-aligned position. No additional energy is required to hold the linkage in the over-center positions.
