Abstract: Embodiments of a multi-waveband sensor system and method for seeking targets are generally described herein. In some embodiments, the multi-waveband sensor system includes 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. The multi-waveband sensor system may also include a laser waveband dichroic beam splitter positioned within a focal path of the secondary reflector to pass infrared (IR) wavebands and to reflect laser wavebands. A LADAR subsystem may transmit laser wavebands for reflection by the laser waveband dichroic beam splitter through the aperture to the secondary reflector for reflection to an off-axis region on the primary reflector for direction toward a target.

Abstract: A multi-spectral reticle projector coaxially projects two separate reticles at different wavelengths through a single aperture by using a lens system including a dichroic lens disposed coaxially between the two reticles. The visible light is reflected by the mirror and passes through the lens system twice, while the infrared light passes through the mirror and passes through the lens system once. At the output of the lens system, the two reticle images are superimposed, collinated and coaxial.
