1. A system for providing real-time image control and processing for use in wide area space based surveillance utilizing an Optical Tera-bps Satellite (OPTSAT) network, including a plurality of OPTSATs, the system comprising:

  • at least one surveillance aperture, on-board one of the plurality of OPTSATs, for optically imaging an object, wherein the surveillance aperture on-board the OPTSAT receives an optical signal representative of an optical image of the object;

    at least one image processor for processing the optical image obtained by the at least one surveillance aperture; and

    at least one terminal capable of wirelessly transceiving information between the at least one terminal and the at least one of the plurality of OPTSATs, the at least one terminal includes a display for displaying the optical image,wherein the at least one surveillance aperture is connected to a multiple beam optical array transceiver comprising;

    at least one receive amplifier for amplifying received optical signals;

    at least one micro-electronic mechanical (MEM) mirror for reflecting free-space optical signals;

    at least one bi-directional optical coupler connected to the receive amplifier, and associated with the MEM mirror, for receiving from the connected amplifier an optical signal, and reflecting a free-space optical signal onto and receiving a reflected free-space optical signal from the associated MEM mirror; and

    a controller for controlling the aiming of the MEM mirror.
