3D spectroscopy with an imaging FTS

Abstract

Among the solutions for 3D spectroscopy, an Imaging Fourrier Transform Spectrometer (IFTS) has the unique capability of making possible flexible high spectral resolution on a wide field. After a brief review of scientific programmes which need this combination, illustrated with results from BEAR, a prototype IFTS, the perspectives for IFTS at Dome C and on an ELT are presented. © 2007 Springer-Verlag Berlin Heidelberg.
