Abstract: | We present TUNIS, a double‐pass spectro‐imager built in THEMIS as a proof‐of‐concept for EST. Basic concepts and selected first results are shown. We introduce the concept of a Hadamard spectral mask as a proposition to move forward from the present implementation of a single‐wavelength per image pixel to a more general one of multiplexed spectral information that improves the temporal coherence of the spectral measurement (© 2010 WILEY‐VCH Verlag GmbH & Co.
