Abstract

Dual-magnification technique for the reduction of moire artifacts, the aliasing of periodic targets caused by sub- sampling, by using two aliased frames of the same periodic target with different optical magnifications is proposed. The technique makes aliasing noise be the source of higher frequency extraction so that superresolution is realized. Simulations and experimental results are presented.
