Abstract :
We describe a spectropolarimeter in the terahertz range (0.25-1.7 THz). The possiblility of simultaneously measuring spectra for unpolarised, linearly and circularly polarised radiation has numerous applications in various fields. A compact modulating system and it´s efficiency are described together with it´s extension to an imaging instrument.
