Detector Correction

Detector corrections reconstruct the original input data from the detector's output data.
This is done by a deconvolution procedure.

In an ideal detector, output data are directly proportional to input data.
Im most real cases this cannot be realized. Two typical effects do modify the input:

Nonlinearity: In modern detectors, this is an obsolete problem, since internal hardware always performs the necessary corrections.

Convolution: Input data are flattened and delayed. In most cases theis traces back to

Convolution errors can be corrected very robustly an calculation times are below seconds.
