MULTI-AXIS, LARGE TILT ANGLE, WAFER LEVEL MICROMIRROR ARRAY FOR LARGE SCALE BEAM STEERING APPLICATIONS

摘要

A system (120) for reflecting or redirecting incident light, microwave or sound energy includes a first substrate (144) configured to support an array of reflective elements (130) that can be angularly displaced through a range of substantially (90) degrees in response to a reflector angle control signal and a controller programmed to generate the reflector angle control signal to achieve desired incident energy, beam or wavefront re-direction. The reflective elements (130) preferably comprise MEMS micro-reflector elements hingedly or movably attached to the first substrate (130) and define a reflective surface that is aimed at the source of incident light, microwave or sound energy.
