apply_volts_and_get_slopes()

def shesha.supervisor.optimizers.calibration.Calibration.apply_volts_and_get_slopes	(		self,
		int	controller_index,
		*bool	noise = False,
		bool	turbu = False,
		bool	reset = True
	)

Apply voltages, raytrace, compute WFS image, compute slopes and returns it.

Parameters

controller_index	(int) : Controller index
noise	(bool) : Flag to enable noise for WFS image computation. Default is False
turbu	(bool) : Flag to enable atmosphere for WFS phase screen raytracing. Default is False reset : (bool) : Flag to reset previous phase screen before raytracing. Default is True

compute_modal_residuals()

np.ndarray shesha.supervisor.optimizers.calibration.Calibration.compute_modal_residuals	(		self,
		np.ndarray	projection_matrix,
		*np.ndarray	selected_actus = None
	)

Computes the modal residual coefficients of the residual phase.

   It supposed that roket is enabled, and the associated GEO controller is index 1.

   Uses the projection matrix computed from compute_modes_to_volts_basis (modalBasis module)

Parameters

projection_matrix	(np.ndarray) : Modal projection matrix
selected_actus	(np.ndarray) : TODO : description

Returns

ai (np.ndarray) : Modal coefficients

		int	controller_index,
		np.ndarray	ampli,
		np.ndarray	modal_basis,
		*bool	noise = False,
		int	nmodes_max = 0,
		bool	with_turbu = False,
		bool	push_pull = False
	)

Computes an interaction matrix from provided modal basis.

Parameters

controller_index	(int) : Controller index
ampli	(np.ndarray) : amplitude to apply on each mode
modal_basis	(np.ndarray) : modal basis matrix
noise	(bool) : Flag to enable noise for WFS image compuation. Default is False
nmodes_max	(int) : Default is 0. TODO : description
with_turbu	(bool) : Flag to enable atmosphere for WFS phase screen raytracing. Default is False push_pull : (bool) : If True, imat is computed as an average of push and pull ampli on each mode

Returns

modal_imat (np.ndarray) : Modal interaction matrix

		int	nmodes_max = 0,
		bool	with_turbu = False,
		bool	push_pull = False,
		int	wfs_index = 0
	)
