make_power_law_error¶

hcipy.optics.make_power_law_error(pupil_grid, ptv, diameter, exponent=- 2.5, aperture=None, remove_modes=None)¶

Create an error surface from a power-law power spectral density.

Parameters

pupil_gridGrid: The grid on which to calculate the error.
ptvscalar: The peak-to-valley of the wavefront aberration in meters.
diameterscalar: The diameter over which the ptv is calculated.
exponentscalar: The exponent of the power law.
apertureField: The mask over which to calculate the ptv. A circular aperture with diameter diameter is used if this is not given.
remove_modesModeBasis: The modes which to remove from the surface aberration. The peak-to-valley is enforced before these modes are removed. This allows for correctting surface errors with optic alignment.
