Autofocus
The class pystages.Autofocus
eases focusing the Z-axis of a stage onto
a tilted XY plane. Given the correct Z position of three points on the XY plane,
the helper class can calculate the correct Z position for any arbitrary point on
the plane.
af = Autofocus()
# Register three correct points
af.register(0, 0, 12)
af.register(1, 0, 12.1)
af.register(0, 1, 12.2)
# Get the correct Z position for another point
z = af.focus(1, 1)
