  • Method of detector gain and offset level estimation by means of a variable aperture transmission mechanism
    Patent number: 9602744
    Abstract: The basis of the invention is an apparatus and a process by which a variable aperture stop mechanism coupled with imaging optics and detector processing electronics achieves measurements of detector pixel gain and level offsets without temporarily blocking the scene from the detector, and without the addition of any other exterior calibration equipment.
    Type: Grant
