35-GS-2759 ABSTRACT OF THE INVENTION A slewable projection system of the type having a relatively high-resolution area-of-interest (AOI) scenic portion inset into and blended with a relatively low- resolution field-of-view (FOV) scenic portion of greater areal extent than the high- resolution portion, includes: at least one optical element for providing the low- resolution background image portion; at least one other optical element for providing the high-resolution AOI image portion; an optical combiner receiving the low-resolution and high-resolution image portion; optics for projecting the combined image onto a viewing area; and at least one fiber-optic cable having a multiplicity of fibers for interconnecting the combining element at least one of the two image optics portions and the projecting optics. A fiber-optic element can mechanically decouple the combining and projecting elements, so that high projection slew rates and accelerations can be realized, while also eliminating hard optics associate with image de-rotation and/or focusing. Another fiber-optic element can provide moveable area-of-interest blending at any selected location over the entire area of the background scene, without movement of a projector or other high-mass subassembly. Use of yet another fiber-optic element can facilitate dynamic image merging.
