CoherentTarget models the return from an optically-rough reflector illuminated by temporally coherent light. The reflecting surface is defined by a mesh of points with random uncorrelated OPDs drawn from a uniform distribution with a specified height range. If the propagation mesh does not match the surface mesh, bilinear interpolation is used to obtain the OPD at the points of the propagation mesh.
The surface roughness phase factor can be multiplied by a non-uniform intensity reflectance map.
CoherentTarget has a single WaveTrain input, representing the incident light, and a single WaveTrain output, representing the transmitted (reflected) light.
See the WT User Guide for further discussion of the properties and options of WaveTrain's rough-reflector modules. CoherentTarget, IncoherentReflector and PartiallyCoherentReflector are WaveTrain's three basic physical models for representing wave-optics scattering from an optically-rough surface.
