摘要： The present invention comprises a line scan camera and a variable focus optical element. With the line scan camera, the three dimensional imaging system of the present invention can overcome the speed problems of the area sensor and the variable focus optical element (Micromirror Array Lens) can change depth as fast as the line scan camera refreshes for the next scan so that the line scan camera and the variable focus optical element can be coupled to control optical depth and the linear scan. With help of the present invention scheme, three dimensional scan can be achieved with only one path scan of the line scan. Scheme, apparatus, and method are disclosed in the present invention.

摘要： The present invention provides an optical micromirror device and their array device and method for making the same. By introducing a sub coating layer and an over coating layer with a high reflective metal layer, the reflective layer of the micromirrors is protected from environmental circumstances, oxidation, degradation, acid, base, and galvanic corrosion of the micro-mechanical structures. Also the new coating structure enhances the performance of the micromirror array device by reducing degradation of the reflectivity of the metal layer, by providing anti-reflection in the optically non-effective area, and by protecting the micro-mechanical structures.

摘要： A Micromirror Array Lens comprises a plurality of micromirrors arranged on a flat or a curved surface to reflect incident light. Each micromirror in the Micromirror Array Lens is configured to have at least one motion. The Micromirror Array Lens forms at least one optical surface profile reproducing free surfaces by using the motions of the micromirrors. The free surface can be any two or three-dimensional continuous or discrete reflective surface. The Micromirror Array Lens having the corresponding optical surface profile provides optical focusing properties substantially identical to those of the free surface. The Micromirror Array Lens can forms various optical elements such as a variable focal length lens, a fixed focal length lens, an array of optical switches, a beam steerer, a zone plate, a shutter, an iris, a multiple focal length lens, other multi-function optical elements, and so on.
