1D Flat-top laser beam ISO measurements

This code can be used to calculate the Flatness (F), Edge-Steepness (S), Beam-Uniformity (U) and Plateau-Uniformity (Up) of a Flat-Top beam.

Following the ISO standards, Flat-Top beams can be quantified by their flatness (F), edge-steepness (S), beam-uniformity (U) and plateau-uniformity (Up).

Included functions: ( Each function file has additional comments)

F = Flatness(I);
S = EdgeSteepness(I);
U = BeamUniformity(I);
Up = PlateauUniformity(I);
d = fwhm(I)

(NOTE!! The input "I" must be a 1D array containing the intensity of the beam at each position I(x))
