Abstract
The measurement of light polarisation is one of the principal means of investigating the interaction of light with matter. One of the most versatile and sensitive instruments for measuring light polarisation is the photoelastic modulator (PEM), a piezoelectrically-driven device with oscillating birefringence that phase-modulates the component of a transmitted electromagnetic wave along the modulation axis. Accompanied by synchronous (phase sensitive) detection, the PEM has figured prominently in a wide range of physical measurements such as circular dichroism, for which it was initially developed', optical rotary dispersion and Faraday rotation, polarimetry of astronomical objects, and strain-induced birefringence2,3,4, ellipsometry5.
