Abstract
Fourier Transform Spectrometers (FTS) are very useful for ECE measurements since they can beabsolutely calibrated by standard blackbody sources, so that independent electron temperaturemeasurements can be obtained. The simultaneous use of several Spectrometers is often required,either to analyse two dimensional configurations or to study the spatial distribution of suprathermalelectrons.The path difference in conventional FTS is scanned by translating a plane mirror; an alternativescheme is based on the rotation of a screw shaped reflector; this makes possible the development ofmultichannel instruments with a single, very fast scanning device.
