A compact and robust method for full Stokes spectropolarimetry

open access: yes, 2012
We present an approach to spectropolarimetry which requires neither moving parts nor time dependent modulation, and which offers the prospect of achieving high sensitivity. The technique applies equally well, in principle, in the optical, UV or IR.
