  • Lenslet array based integral field spectrograph and data processing
    Patent number: 10236166
    Abstract: A lenslet based integral field spectrograph (IFS) may have a design that makes better use of the detector pixels by placing adjacent spectra next to each other rather than staggering the spectra. Such a design maintains the main compactness and simplicity of prior lenslet array based IFSs, but improves the detector efficiency, which is rather low in conventional lenslet array based IFSs.

  • Systems and methods for mirror mounting with minimized distortion
    Patent number: 8092031
    Abstract: A method for mounting a mirror for use in a telescope includes attaching the mirror to a plurality of adjustable mounts; determining a distortion in the mirror caused by the plurality adjustable mounts, and, if the distortion is determined to be above a predetermined level: adjusting one or more of the adjustable mounts; and determining the distortion in the mirror caused by the adjustable mounts; and in the event the determined distortion is determined to be at or below the predetermined level, rigidizing the adjustable mounts.
