FixedOpdMap models the optical effects of a transverse OPD (phase) map, which is applied to both incoming and outgoing light. The OPD map is assumed to be fixed in time. The OPD map is specified in DISTANCE units (m), which the module will convert to phase lags that depend on the wavelength of the passing wave(s).

The OPD map is specified by a parameter of type Grid<float>. See the LightLike User Guide for methods of creating and inputting Grid data types.

There is a related module, called OpdMap, which allows the specification of a time-varying transverse OPD map.
