Abstract: The present disclosure relates to a thermal emissivity control system. The system may have a segmented array that makes use of a thermally conductive base layer configured to be connectable to an external heat generating subsystem, with the base layer including a thermally emissive surface. The array may also have a plurality of actuation elements at least one of positioned on or adjacent to the thermally emissive surface. A plurality of movable shutter elements is disposed adjacent one another in a grid pattern, and controlled in movement by the actuation elements to create gaps of controllably varying dimension therebetween. The shutter elements control at least one of a magnitude of, or direction of, thermal radiation through the gaps.

Abstract: The present disclosure relates to a system for modifying temporal dispersion in an optical signal. The system makes use of a segmented array including a plurality of independently controllable, reflective optical elements. The optical elements are configured to segment a received input optical signal into a plurality of beamlets, and to reflect and steer selected ones of the plurality of beamlets in predetermined angular orientations therefrom. A variable optical dispersion subsystem is used which has a plurality of optical components configured to receive and impart different predetermined time delays to different ones of the received beamlets, and to output the plurality of beamlets therefrom.
