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.

摘要： This invention provides a Hybrid Micromirror Array Lens with reduced chromatic aberration over a broadband wavelength range of light. Conventional micromirror array lens uses phase matching condition. Therefore, the optical surface profile of Micromirror Array Lens using the same phase condition has a discontinuous surface profile. As the required optical power of Micromirror Array Lens is increased, the number of profile discontinuity of Micromirror Array Lens is increased. Therefore, the chromatic aberration is increased. To minimize the chromatic aberration, the number of profile discontinuity should be minimized. The number of discontinuity is reduced when the optical surface profile has a simulating base curve, called a translation contour with optical power. Hybrid Micromirror Array Lens is invented to reduce a large translational amount and chromatic aberration for large optical power lens.
