Abstract

This paper shows an approach using tunable narrowband speckle pattern generated by a double-slit aperture laid behind a new microcrystalline glass material scattering screen, for testing MTF of FPA between zero and twice Nyquist frequency. The measurement near to the Nyquist frequency, this method proved highly effective much better than that obtained by the Wide-band Laser Speckle.
