abstract
2015 SPIE. A hybrid platform is proposed for optical processing with capabilities beyond the standard use for spatial filter coefficients. Time domain operations are explored utilizing electro-optical components to generate and steer an optical beam across the digital micro-mirror device (DMD). An input signal in the form of a collimated optical beam is scanned through an imaging optic across the DMD to achieve 1-D operations. Coefficient "bit depth" is determined by the mirror pattern in the local spot zone giving a ratio of "on" state to "off" state area. The reflected signal returns along the original path through the imaging lens and is read by a receiver. Design feasibility is presented along with initial experimental results.
