rulings

Periodic rulings which can be added to an optical surface to model a diffraction grating.

Functions

incident_effective(wavelength, direction, ...)

The effective propagation direction of some rays incident on a diffraction grating.

Classes

AbstractRulingSpacing()	An interface describing the instantaneous ruling spacing on the surface of a diffraction grating.
ConstantRulingSpacing(constant, normal)	The simplest type of ruling spacing, a constant distance between each ruling.
Polynomial1dRulingSpacing(coefficients, normal)	Ruling spacing specified by a 1-dimensional polynomial.
HolographicRulingSpacing(x1, x2, wavelength)	Rulings created by interfering two beams.
AbstractRulings()	Interface for the interaction of a ruled surface with incident light
