Abstract: A first embodiment includes a set of diffraction gratings on the face of a wheel, each grating being set at an angle to select a different spectral line. The wheel is rotated, and as each grating moves into the end-reflector position of the laser's optical path, the laser is fired. Alternate embodiments include a small spinning fold mirror that reflects the beam in a circle about the axis of the laser. Such embodiments include (a) a circular array of diffraction gratings arranged about the laser axis such that the tilt of the gratings and the orientation of the grooves vary as one goes around the circle and successively fires the laser at each grating; (b) both a circular array of mirrors and a corresponding array of diffraction gratings such that the grooves of all of the gratings are parallel and the gratings are all tilted in the same direction; and (c) two spinning fold mirrors and two circular arrays of mirrors giving a double fold plus a single diffraction grating wherein the optical paths are not parallel but arrive at the grating at different angles for selecting different spectral lines.

Abstract: An optical receiver system operative to allow a set of fixed positioned detectors in the same Dewar to be optically directed to concurrently sense any subset of a known set of spectral lines. The system also has a transmitter mode that allows a group of radiation sources having a subset of a possible set of spectral lines to be relatively optically overlapped at the transmitter aperture.
