  • Spatial light modulator apparatus and method
    Patent number: 7532323
    Abstract: A device for discriminately illuminating a sample (22) to be viewed with excitation light (70). For example, an image taken with a CCD (10) provides feedback which is used to modulate the output of an excitation light source (40), thereby allowing a sample (22) to be viewed within the optimal range of detection for the particular CCD device (10) being used, despite the potential of wide dynamic ranges of sample luminescence.
    Type: Grant
    Filed: October 28, 2004
    Date of Patent: May 12, 2009
    Inventors: Cha-Min Tang, Andrew Bartfay-Szabo
