Abstract
This invention pertains to a basic multi-technology application of cascaded beam-formers. A dual MEMS-EO technology platform method involving a two axis deflection micro-mirror cascaded with a three dimensional electro-optical beam-former such as a multi pixel liquid crystal device forms a powerful reflective control site for an incident beam, thereby inherently providing a robust beam control with both coarse and fine beam control capabilities in three dimensions. The electrically controlled two axis micro-mirror is excellent in providing the large angular beam deflections, while the liquid crystal device provides excellent small-beam deflections. This leads to a mechanically robust beam control module. A multipixel MEMS mirror device option coupled with the EO device can also provide simultaneous multi-beam generation capability. Furthermore, use of macro-pixels for both the MEMS and EO devices provides resistance to single pixel dependent catastrophic failure for the overall module. The mirror two-axis control can be supplemented with additional translational mirror motion, giving the ultimate option of cascading two 3-D beam-formers.
