Abstract: To maximize the light capturing and imaging resolution capability of an imaging satellite while minimizing weight, the primary reflector and other elements of the optical path have a shape optimized to the shape of the satellite. For a nanosatellite with a square cross-section, the first mirror and other elements of the telescope section in the optical path have a square cross-section, as does the sensor array of the camera section.

Abstract: A satellite imaging system uses multiple cameras. For example, the incoming light from a telescope section of the satellite goes through a dichroic beam splitter, with the standard visible spectrum going to a first camera and wavelengths outside of the standard visible spectrum, such as in the infrared or coastal blue range, are sent to a second camera, allowing image data from multiple wavelength ranges to be captured simultaneously. The image data from the different wavelengths of the two cameras can then be selectively recombined. In a more general case, there is a first range of wavelengths and a second range of wavelengths.

Abstract: A satellite imaging system includes a camera with a pixel shifting mechanism, thermally stable imaging payload, and high-stability attitude determination and control system (ADCS) to improve image resolution. To address the overall stabilization requirement, the satellite incorporates a number of design elements that, in combination, provide the stable result required for good imaging.

Abstract: A scanning system which utilizes a resonant mechanical oscillator, such as a galvanometer, to scan a laser beam across a surface of a medium responsive to said laser beam. The laser beam scan velocity across the surface normally would vary sinusoidally because of the resonant nature of the drive system. The data flow, or bit density, of information to be recorded on or read out from the surface, would have a corresponding sinusoidal variation. In order to compensate for this, a grating is provided adjacent the galvanometer and a second laser beam is simultaneously incident on the mirror portion of the rotating galvanometer. As the galvanometer is caused to oscillate, two scanning beams are generated, one scanning the surface and the other scanning across the grating.

Abstract: A laser scanning system for scanning an original color document with light of three different colors. In a first operative sequence, the output beam from a laser, which comprises light of a first color, is incident upon a rotating scanning member, the light therefrom being directed to a reflecting first portion of a luminescent screen, the light reflected from said first screen portion completely scanning the entire original document. In a second operative sequence, the laser light from said rotating scanning member is directed to a second portion of said luminescent screen having a material associated therewith which produces light of a second color in response to the incident laser light, the light produced by said second portion of said luminescent screen scanning the entire original document.
