BesselProbe

class diffsims.utils.probe_utils.BesselProbe(r)

Bases: ProbeFunction

Probe function given by a radially scaled Bessel function of the first kind.

Parameters:

r (float) – Width of probe at the surface of the sample. More specifically, the smallest 0 of the probe.

Methods

BesselProbe.FT(y[, out])

If Y = sqrt(y[...,0]**2 + y[...,1]**2)*r then returns an indicator function on the disc Y < 1, y[2]==0.
