Abstract

New double exposure speckle techniques for imaging system analysis are developed and their feasibility is experimentally examined. Using a single convex lens as the test lens, the MTF of the lens is obtained from the measured visibility of Young's fringes which have been produced by Fourier transforming a double exposure specklegram recorded through the test lens. By using conventional optical filtering techniques the spatial variations in the imaging quality are visualized for GRIN rod lens arrays.
