do_specific_progation(wavefront, propagation_distance, parameters=None, element_index=None)[source]

Propagate a 1-D wavefront using direct spatial-domain convolution with the Fresnel kernel.

Parameters:

  • wavefront (GenericWavefront1D) – Input wavefront.

  • propagation_distance (float) – Propagation distance [m].

  • parameters (PropagationParameters, optional) – Propagation parameter container.

  • element_index (int, optional) – Index of the beamline element being propagated through.

Returns:

Propagated wavefront with energy-conserving normalisation applied.

Return type:

GenericWavefront1D
