Beam Shape Coarse¶
The BeamShapeCoarse device integrates the incoming images in Y and X directions, then finds the position of the peak and the beam size on such integrals.
Position and size of the beam are calculated with the peakParametersEval function from the image processing package, thus the evaluated values make sense only if the peak has a single maximum. Also noise (ripple) may affect the result.
