| 20100245976 | DIGITAL BINARY MEMS WAVEFRONT CONTROL - Embodiments of the invention are directed to a new type of phase screen, i.e., an opto-electronic device that can convert a distorted incoming optical wavefront into a plane wave or, conversely, transform a plane wave into a prescribed varying output wavefront. The basic concept involves novel binary all-digital MEMS interferometer configurations that can be used to create controlled and arbitrary optical wavefront using only 0,1 amplitude changes followed by differential propagation distances to convert these amplitude variations into controllable and/or continuous phase variations. Clustered pixel notions, such as Floyd-Steinberg, Stucki or other algorithms useful in digital half-tone printing, are simultaneously employed to create controllable grey-level variations as well as continuous phase variations. Desired grey-levels can be obtained wherein each pixel is formed by, e.g., a 3×3 or 5×5 cluster of mirrors. Both the filling-in of the outputs of the binary mirror (0,1) and the grey-levels are accomplished simply by spatial averaging over a short propagation distance. | 09-30-2010 |
| 20110085051 | OPTICAL ELEMENT, DEVICE, METHOD, AND APPLICATIONS - A novel phase-coded aperture, associated imaging system, and design method is disclosed.

A diffraction pattern in the form of a band-limited uniformly redundant array is formed on the detector array when focusable radiation from a point source in object space is modulation by the transmission function of the coded-aperture. Since diffraction effects cannot be ignored in the optical regime, an iterative phase retrieval method is used to calculate the phase-coded aperture transmission function. Correlation type processing can be applied for the image recovery. | 04-14-2011 |
