NeuNorm

NeuNorm: neutron imaging normalization library. NeuNorm is an open-source Python library that normalized neutron imaging measurements. In order to cancel detector electronic noises, source beam fluctuations and other pollution signals from close by beam lines, every data acquired need to be normalized. In order to perform the normalization, one must take, in addition to his data set, either 1 or 2 extra data set. A set of open beam (OB) when sample has been removed but beam is on. An optional set of dark field (DF) is taken when beam is off and sample off. The dark field allows to clean the electronic noises from the images. The principle of normalization can be summarized by the following figure.
