Fabry-Perot data cubes. Introduction: what is "data cubes"? Observations with the IFP consist of successive acquisition of a few dozen images of interference rings from the object (or from a calibration lamp) when changing the optical path between the flat-parallel plates. The radius of the rings is a function of wavelength and gap between the plates of the interferometer. ... Its interference rings of Ne line which use for phase calibration (convert object data to wavelength-scale). ...
