OpdMap models the optical effects of a transverse OPD (phase) map, which is applied to both incoming and outgoing light. The OPD map is allowed to be time-varying. 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 an input of type Grid<float>. See the TimeLike User Guide for methods of creating and inputting Grid data types.

There is a related module, called FixedOpdMap, which can be used if the transverse OPD map is constant in time. The only difference between the two modules is that the map is entered as an input in the present module, but as a parameter in the other.
