  • Device, system, and technique for characterizing a focal plane array modulation transfer function
    Patent number: 10267684
    Abstract: An apparatus, system, and method to characterize a focal plane array. The apparatus includes a speckle field source to generate and emit a plurality of uniform speckle fields, a diamond-shape aperture, and a pedestal to mount the focal plane array at a predetermined distance from the aperture. The diamond-shape aperture shapes the uniform speckle fields from the speckle field source so that the uniform speckle fields have a desired power spectral density at the focal plane array. The desired power spectral density has recoverable aliased regions out to two times the Nyquist frequency of the focal plane array. The system includes a controller to characterize, by computing a modulation transfer function, the focal plane array based on the desired power spectral density of the uniform speckle fields impinging on the focal plane array.
