Core Data Model

These types define the basic objects passed through an optical stack. In the source tree, the sampling primitives live in src/fouriax/optics/grid.py and the field containers live in src/fouriax/optics/field.py.

Grid	Regular 2D sampling lattice with pixel spacing in micrometers.
AngularGrid	Regular 2D angular sampling lattice with step sizes in radians.
Spectrum	Immutable collection of wavelengths in micrometers.
Field	Complex optical field over a 2D grid for one or more wavelengths.
Intensity	Real-valued spatial intensity over a 2D grid for one or more wavelengths.
OpticalModule	Sequential container for optical layers and monitor checkpoints.
