FourierTransform

class hcipy.fourier.FourierTransform

Bases: object

The base class for all Fourier transform implementations.

Attributes

input_gridGrid

The grid that is expected for the input field.

output_gridGrid

The grid that is produced by the Fourier transform.

Methods Summary

backward(self, field)	Returns the inverse Fourier transform of the Field field.
