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.
