This paper deals with diagnostic methods in fusion-oriented plasma research which utilise electromagnetic radiation with wavelengths between about 0.1 and 10 mm. This spectral range not only encompasses the electron cyclotron emission (yielding information on the temperature distribution) but is also most appropriate to exploit the parameter dependence of the refractive index for measuring electron densitites and magnetic fields within large high-temperature plasmas. The underlying physical principles and practical implementations of passive electron-cyclotron-emission (ECE) diagnostics as well as the application of microwave and far-infrared laser beams reflectometry, interferometry and polarimetry are presented.
