Abstract: A system may include a processor, a night vision sensor, and an objective lens assembly comprising four lenses. Each of a first lens, a second lens, a third lens, and a fourth lens may be configured to project a real world scene onto one of four portions of the night vision sensor. The night vision sensor may be configured to provide four images of the real world scene from the objective lens assembly to the processor. The processor may be configured to: receive a first image, a second image, a third image, and a fourth image from the night vision sensor; generate color night vision image data based at least on the first image, the second image, the third image, and the fourth image; and output the color night vision image data.

Abstract: A gimbal for a gimbaled mirror optical sensor system includes a mirror support rotatable about a first axis along which an optical sensor suite lies, the first axis being spaced apart from a desired pivot point of a variable line of sight, which may be for example a fixed-size window in the outer wall of an aircraft. The gimbal further includes two generally planar mirrors supported by and rotatable with the mirror support. A first mirror is spaced apart from the optical sensor suite along the first axis and is non-orthogonal to the first axis so as to reflect light from a second axis to the optical sensor suite, wherein the second axis sweeps an arcuate path about the first axis upon rotation of the mirror support. A second mirror lies along the second axis so as to follow the arcuate path upon rotation of the mirror support. The second mirror is pivotable so as to reflect light from the variable line of sight to the first mirror along the second axis.
