Abstract:
1. A multi-waveband sensor system comprising: a secondary reflector positioned within a gathering path of a primary reflector to reflect the wavebands gathered by the primary reflector back through an aperture in the primary reflector; a laser waveband dichroic beam splitter to pass infrared (IR) wavebands and to reflect laser wavebands; and a LAser Detection And Ranging (LADAR) subsystem to transmit LADAR pulses within the laser wavebands and to process LADAR returns, wherein the laser waveband dichroic beam splitter is positioned within a focal path of the secondary reflector to: pass the IR wavebands reflected by the secondary reflector through to an IR waveband receiver; reflect the LADAR pulses through the aperture to the secondary reflector for reflection to an off-axis region on the primary reflector for direction toward a target; and reflect the LADAR returns to the LADAR subsystem that are gathered by the primary reflector and reflected by the secondary reflector through the aperture.
