class hcipy.wavefront_sensing.OpticalDifferentiationWavefrontSensorEstimator(slope_grid, aperture)¶

Bases: hcipy.wavefront_sensing.wavefront_sensor.WavefrontSensorEstimator

Estimates the wavefront slopes from pyramid wavefront sensor images.

Parameters

aperturefunction: A function which mask the pupils for the normalized differences.
output_gridGrid: The grid on which the output of a pyramid wavefront sensor is sampled.

Attributes

measurement_gridGrid: The grid on which the normalized differences are defined.
pupil_maskarray_like: A mask for the normalized differences.
num_measurementsint: The number of pixels in the output vector.

Methods Summary
