PhaseGrating
- class hcipy.optics.PhaseGrating(grating_period, grating_amplitude, grating_profile=None, orientation=0)[source]
Bases:
OpticalElementA grating that applies an achromatic phase pattern.
- Parameters:
- grating_periodscalar
The period of the grating.
- grating_amplitudescalar
The amplitude of the grating.
- grating_profilefield generator
The profile of the grating. The default is None and assumes a sinusoidal profile for the grating.
- orientationscalar
The orientation of the grating in radians. The default orientation is aligned along the y-axis.

- backward(wavefront)[source]
Propagate a wavefront backward through the optical element.
A backward propagation is a literal backward propagation through the element. It is not (in general) the inverse of the forward propagation, except in cases where energy is conserved.
This function will be implemented by the derived class.
- Parameters:
- wavefrontWavefront
The wavefront to propagate.
- Returns:
- Wavefront
The propagated wavefront.
