Abstract

The image quality of a discretely reconstructed image depends directly on the pixel exposure profile of the discrete image recorder. By minimizing the mean-square error (MSE) of the recorded signal, optimum intensity and exposure profiles can be derived. This paper develops a method based on minimum MSE for determining the optimal exposure profile for an assumed sampling lattice and analog signal spectrum, and determines a physically realizable approximation to this profile by amplitude phase modification of the source–amplitude distribution.
