WavefrontError¶

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

Bases: poppy.optics.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

wave : Wavefront: 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
