DeformableMirror¶

class hcipy.optics.DeformableMirror(influence_functions)¶

Bases: hcipy.optics.optical_element.OpticalElement

A deformable mirror using influence functions.

This class does not contain any temporal simulation (ie. settling time), and assumes that there is no crosstalk between actuators.

Parameters

influence_functionsModeBasis: The influence function for each of the actuators.

Attributes Summary

`actuators`
`influence_functions`	The influence function for each of the actuators of this deformable mirror.
`num_actuators`
`opd`	The optical path difference in meters that this deformable mirror induces.
`surface`	The surface of the deformable mirror in meters.

Methods Summary

`backward`(self, wavefront)	Propagate a wavefront backwards through the deformable mirror.
`flatten`(self)	Flatten the DM by setting all actuators to zero.
`forward`(self, wavefront)	Propagate a wavefront through the deformable mirror.
`phase_for`(self, wavelength)	Get the phase in radians that is added to a wavefront with a specified wavelength.
`random`(self, rms)	Set the dm actuators with random white noise of a certain rms.
