IBIS (INTERFEROMETRIC BIDIMENSIONAL SPECTROMETER)

摘要

IBIS is a new instrument for solar bidimensional spectroscopy, now under construction at the Arcetri Astrophysical Observatory. It essentially consists in two Fabry-Perot interferometers, used in classic mount and in axial mode, in series with a set of narrow band interference filters. This instrument will operate on a large wavelength range, with high spectral, spatial and temporal resolution. Some preliminary results, obtained during the ongoing evaluation of the instrumental set-up, will be described.
