Abstract: In Fourier transform spectroscopy, path difference dependent misalignments, such as those due to imperfect mechanical/movement of the scanning mirror, can be modelled as path difference dependent apodization and phase errors. The theoretical model that relates the mirror drive characteristics to the path difference dependent error is used to verify the consistency of the optical instrument line shape with the measurements of the mechanical drive quality. This procedure can be used as a diagnostic and qualification tool.
