title: Vernier scaling in shortened optical correlators.
abstract: Vernier transform scaling is achieved in a shortened optical correlator by placing the input spatial light modulator (SLM) between the telephoto transform lens pair. Translating the SLM changes the Fourier transform scale but not the position of the transform plane.
