Development of a Mercury Bromide Birefringence Measurement System Based on Brewster’s Angle [PDF]
Mercury bromide (Hg2Br2) has been used to develop acousto-optic tunable filters (AOTFs) because it has several advantages, including a high refractive index, a broad optical bandwidth, and a relatively high figure of merit.

Birefringence measurements on crystalline silicon [PDF]
Crystalline silicon has been proposed as a new test mass material in third generation gravitational wave detectors such as the Einstein Telescope (ET). Birefringence can reduce the interferometric contrast and can produce dynamical disturbances in interferometers.

Polymer Relaxation Times from Birefringence Relaxation Measurements [PDF]
A theoretical description of the time dependence of induced birefringence in polymers, based on the ``pearl-necklace'' model, is presented, and relations between relaxation and frequency dependence methods are discussed. The relaxation theory is applied to the results of measurements of the longest relaxation time for the DNA from bacteriophage T2. The
