Integration and testing of FTS-2: an imaging Fourier transform spectrometer for SCUBA-2

摘要

FTS-2 is an imaging Fourier transform spectrometer (IFTS) being developed for use with SCUBA-2, the secondgeneration, wide-field, submillimetre camera which will operate at the James Clerk Maxwell Telescope (JCMT). TheFTS-2 interferometer uses a folded Mach-Zehnder configuration and will provide simultaneous broadband spectralimaging across both the 850 and 450 μm bands with variable resolution ranging from resolving powers of R ~10 to5000. Details of the instrument design, optical modeling, data reduction pipeline and calibration plan which havechanged since the project CDR are discussed, along with preliminary results of lab integration and testing.
