  The combination of interaction-free measurement and the quantum Zeno effect
has been shown to both increase the signal-to-noise ratio of imaging, and
decrease the light intensity flux through the imaged object. So far though,
this has only been considered for discrimination between translucent and opaque
areas of an object. In this paper, we extend this to the polarimetry of a given
sample. This will allow the identification and characterisation of these
samples with far less absorbed energy than current approaches -- a key concern
for delicate samples being probed with high-frequency radiation.
