Programming a Detector Summing Square Amplitude on Optical Axis

By means of the example, it is intended to illustrating the access on field values in a Programmable Detector via source code. The programmable detector calculates the sum of all squared amplitudes on the optical axis including all field components. As an example, the detector is applied on a donut mode, which is modeled as the combination of a HG01 and a HG10 Hermite Gaussian modes.
