pysrw.lib.srwlib.SRWLOptShift

class pysrw.lib.srwlib.SRWLOptShift(_shift_x=0, _shift_y=0)

Bases: SRWLOpt

Optical Element: Shirt

__init__(_shift_x=0, _shift_y=0)

Parameters:

• _shift_x – horizontal shift [m]

• _shift_y – vertical shift [m]

Methods

__init__([_shift_x, _shift_y])	param _shift_x: horizontal shift [m]
get_orient([_e])
randomize()	Randomizes parameters of optical element according to self.RandParam to simulate e.g. impact of vibrations on coherence (in P-C calculations).
set_rand_par(_rand_par)	Sets list of params to be eventually randomized in some types of calculations :param _rand_par: list of params to be randomized; each element of this list should be: ['param_name', val_avg, val_range, meth]
