Imaging interferometer transfer function correcting method, involves adapting composition of sub-pupils` sub-assemblies of interferometer and sequence of acquisitions of chosen sub-assemblies to select frequency components in Nyquist square
Résumé
The method involves performing separate acquisitions of selected sub-assemblies of sub-pupils (401) of an imaging interferometer. The sub-assemblies are selected to improve the form of modulation transfer function of the interferometer. The composition of the sub-assemblies and sequence of the acquisitions are adapted for selecting the perceptible frequency components inside the Nyquist square associated to sampling.
