摘要：

Electron cyclotron emission spectra are routinely measured in the FTU tokamak by means of a fast scanning Fourier transform spectrometer. The key element of this instrument is a two-beam interferometer in which the path difference is varied linearly in time by rotation of a helicoidal reflector. The shortest scan time obtained for a path difference excursion of 4 cm was 1.2 ms. The spectrometer has been absolutely calibrated and the measured temperature profiles are in good agreement with those derived from other diagnostics. (C) 1995 American Institute of Physics.
