20080225370 | Low-cost continuous phase sheet deformable mirror - This continuous phase sheet deformable mirror leverages advances in polymer manufacturing to create a low-cost alternative to the existing microelectromechanical system (MEMS) and bulk (piezoelectric and electrostrictive) deformable mirror technology. These novel mirrors can be used for any form of phase control including but not limited to piston control, beam steering, and higher order adaptive optics. The preferred mirror surface is a pellicle, but any thin polymer high optical quality surface will suffice. The thin polymer phase sheet can be combined with any actuator structure, like those produced by MEMS, to create a higher quality hybrid deformable mirror. | 09-18-2008 |
