  • Patent number: 8659834
    Abstract: A method of making an achromatic gradient index singlet lens comprising utilizing a gradient index material with a curved front surface in which light does not follow a straight line as it travels through the material and wherein different color rays traverse different curved paths, utilizing the natural dispersion of the curved front surface as a strong positive lens, and developing a weakly diverging GRIN distribution within the lens to balance the chromatic aberrations of the curved front surface.

  • Patent number: 8462179
    Abstract: A method and system is provided for performing high-resolution image assembly regardless of observed scene content. An imaging system, including a focal plane array and lenslet array can be calibrated to account for subimage shifts. A calibration module can determine the subimage shifts by calculating an average point source position reference point coordinates for each of the subimages, and then determining the difference between the average point source position and the reference point coordinates for each subimage. The imaging system can then be calibrated utilizing the subimage shifts for each of the plurality of subimages. Finally, an assembly module can perform a high-resolution image assembly with the calibrated imaging system.

  • Publication number: 20020061472
    Abstract: Two programmable masks are used for the exposure of three-dimensional patterns in a photosensitive material. This exposure technique takes advantages of symmetries and repeating structures in the exposure pattern to reduce the exposure time, while maintaining the flexibility to produce complicated three-dimensional shapes.
