Paper Abstract

The fringes produced by a wedge with partially reflecting faces placed in the input plane of a coherent processor are shown to provide a conveniently tunable spatial carrier. This carrier is tunable in frequency and orientation and has a controllable fringe profile. This encoding scheme is ideal for a number of optical processing techniques. Its use for density slicing, an example of a nonlinear operation, is demonstrated.
