A novel projection system includes a base signal source, a highlight signal source, a base/highlight destination, and a shared optical element. A base signal provided by the base source and a highlight signal provided by the highlight source are combined by the shared optical element. In a particular embodiment, the base signal source and the highlight signal source each include a light source, a spatial light modulator, and optics, and the base/highlight destination includes optics and a spatial light modulator. In a more particular embodiment, the base signal source and the highlight source provide spatially modulated lightfields to the shared optical element. In another particular embodiment, the base signal and the highlight signal are modulated by the spatial light modulator of the base/highlight destination after being combined.

A forward-on-forward high dynamic range architecture for digital micromirror devices device is provided. In particular, provided herein is a device that includes two digital micromirror devices (DMDs), each operated in a forward configuration, such that each is illuminated at a respective non-normal angle and a respective output image is reflected at a normal angle, a subject plane of a first DMD being parallel to the first DMD. Optics between the DMDs are configured to convey light reflected from the first DMD to illuminate an image plane at a second DMD in the forward configuration, the optics including an equivalent lens plane. At least one optical device between the DMDs is configured to: tilt the subject plane of the first DMD to an equivalent tilted subject plane, the equivalent lens plane, the equivalent tilted subject plane and the image plane all intersecting at a Scheimpflug intersection.

A compact integrated optical system including an eyepiece, a reflective telescope, and a multi-spectral combiner optically coupled between the reflective telescope and the eyepiece, and configured to direct visible light received via the reflective telescope assembly along a direct view optical path to the eyepiece assembly. In one example, the multi-spectral combiner includes a display that displays a visual representation of the imagery of the viewed scene, and laser range-finder transceiver that transmits and receives a laser beam via the reflective telescope. A pair of beamsplitters is used to separate the imaging optical path from the direct view and laser range-finding optical paths. A blocking device is used to enable laser range-finding capability during daytime viewing of the imaging optical path imagery on the display. The reflective telescope provides a common aperture for the direct view optical path, an imaging optical path, and the laser range-finder transceiver.
