Abstract:
1. A viewing system comprising a spatial light modulator and a light guide bundle having a proximal end and a distal end, wherein spatial light modulator is optically connected to the proximal end of the light guide bundle in a same conjugate image plane as the proximal end such that the spatial light modulator controls the location of light impinging on the proximal end, wherein the spatial light modulator is operably connected to a controller comprising computer-implemented programming configured to set to an on-state pixels of the spatial light modulator corresponding to cores of corresponding light guides in the light guide bundle to provide on-pixels and configured to set to an off-state pixels corresponding to inter-core areas of the light guide bundle to provide off-pixels, wherein the viewing system further comprises a pixelated detector optically connected to receive light emanating from the proximal end of the light guide bundle and the controller further comprises computer-implemented programming that distinguishes between light emanating from the light guides corresponding to on-pixels of the spatial light modulator and light emanating from other light guides, and wherein the controller further comprises computer-implemented programming that detects light emanating from the other light guides to provide out-of-focus data and the programming incorporates the out-of-focus data with the light emanating from the light guides corresponding to the on-pixels to provide an enhanced image.
