Layers And Modules

These classes define the main transform layers used to build optical systems. The implementations are split across layers.py, polarization.py, imaging.py, and propagation.py, but the public API is re-exported from fouriax.

OpticalLayer	Base interface for field-to-field optical transformations.
PhaseMask	Spatial-domain phase-only modulation layer.
AmplitudeMask	Spatial-domain amplitude modulation layer.
ComplexMask	Spatial-domain complex-valued modulation layer.
FourierTransform	Explicit spatial → k-space domain transform layer.
InverseFourierTransform	Explicit k-space → spatial domain transform layer.
KSpacePhaseMask	k-space phase-only modulation layer.
KSpaceAmplitudeMask	k-space amplitude modulation layer.
KSpaceComplexMask	k-space complex-valued modulation layer.
JonesMatrixLayer	Spatial-domain Jones matrix modulation layer.
KJonesMatrixLayer	k-space Jones matrix modulation layer.
ThinLens	Ideal thin lens applying a hyperbolic optical-path phase delay.
