- class hcipy.wavefront_sensing.ZernikeWavefrontSensorEstimator(aperture, output_grid, reference)
Bases:
WavefrontSensorEstimator
Estimates the wavefront slopes from pyramid wavefront sensor images.
- Parameters:
- aperturefunction
A function which mask the output phase measurements.
- output_gridGrid
The grid on which the output of a pyramid wavefront sensor is sampled.
- referenceField
A reference image to subtract from the Zernike wavefront sensor data.
- Attributes:
- measurement_gridGrid
The grid on which the phase measurements are defined.
- pupil_maskarray_like
A mask for the phase measurements.
- num_measurementsint
The number of pixels in the output vector.
- referenceField
A reference image to subtract from the Zernike wavefront sensor data.
