WavefrontError

class poppy.WavefrontError(**kwargs)[source]

Bases: AnalyticOpticalElement

A base class for different sources of wavefront error

Analytic optical elements that represent wavefront error should derive from this class and override methods appropriately. Defined to be a pupil-plane optic.

Methods Summary

`get_opd`(wave)	Construct the optical path difference array for a wavefront error source as evaluated across the pupil for an input wavefront `wave`
`peaktovalley`()	Peak-to-valley wavefront error induced by this surface
`rms`()	RMS wavefront error induced by this surface

Methods Documentation

get_opd(wave)[source]

Construct the optical path difference array for a wavefront error source as evaluated across the pupil for an input wavefront wave

Parameters:

waveWavefront: Wavefront object with a coordinates method that returns (y, x) coordinate arrays in meters in the pupil plane

peaktovalley()[source]: Peak-to-valley wavefront error induced by this surface

rms()[source]: RMS wavefront error induced by this surface
