Stokes polarimeter using two photoelastic modulators
(B. Wang, J. List, R. Rockwell, SPIE Proceedings, vol. 4819, July 2002)
Abstract:
A complete description of a 2 PEM polarimeter. Includes repeatability and sensitivity information.

A Near Infrared Linear Birefringence Measurement System Using a Photoelastic Modulator
SPIE Proceedings, Vol 4399, 89-97, June 2001, B. Wang
This paper describes an instrument to measure linear birefringence using a near infrared (NIR) laser at 1523 nm. The magnitude and angle of the fast axis are simultaneously determined. Accuracy, repeatability, and other performance tests are also provided.

Evaluation Of A Dual PEM Stokes Polarimeter Using Different Signal Processing Methods (B. Wang, A. Leadbetter, R. Rockwell SPIE Proceedings, vol 5888, Aug. 2005)
In our laboratory we built a Stokes polarimeter using two photoelastic modulators (PEMs). We applied two different signal processing methods to this dual PEM Stokes polarimeter. In one method, we used lock-in amplifiers to measure the PEM modulated signals. In the other method, we used Fourier analysis of a digitized waveform that contains the modulated signals. The dual PEM Stokes polarimeter can measure all normalized Stokes parameters. In this paper we present and compare results obtained using both signal processing methods. We discuss how each method benefits selected applications of the dual PEM Stokes polarimeter.
