Digital light deflector using optical resonators
Abstract
Abstract A LIGHT DEFLECTOR IS DISCLOSED WHICH INCLUDES AN INPUT FABRY-PEROT TYPE RESANOTOR, AND AN OUTPUT FABRY-PEROT TYPE RESONATOR. THE TWO RESONATORS ARE SEPARATED BY A TRANSPARENT WEDGE HAVING AN ANGLE A/2. A SOURCE OF A LASER BEAM OF MONOCHROMATIC COHERENT LIGHT IS DIRECTED TO THE INPUT RESONATOR AT AN ANGLE OF INCIDENCE $ (RELATIVE TO A NORMAL REFERENCE LINE) AT WHICH THE RESONATOR EXHIBITS A TRANSMISSION PEAK, SO THAT A BEAM OF LIGHT IS TRANSMITTED INTO AND THROUGH THE TRANSPARENT WEDGE TO THE OUTPUT RESONATOR. MEANS ARE PROVIDED TO VARY A PHYSICAL PARAM- ETER IN THE LIGHT PATH THROUGH THE SECOND RESONATOR IN AMOUNTS TO CAUSE A BEAM OF LIGHT TO EMERGE FROM THE OUTPUT RESONATOR AT ANY ONE OF MANY ANGLES, RELATIVE TO SAID REFERENCE LINE, APPROXIMATELY EQUAL TO 0 PLUS AN INTEGRAL MULTIPLE INCLUDING ZERO OF A. THE PARAMETER VARIED MAY BE THE PHASE DELAY IN THE OUTPUT RESONATOR, OR A PHSYCIAL SPACING OF RESONATOR SURFACES.
