Optometry and Vision Science, 1975
In recent years it has become common for the birefringence pattern of a thermally toughened glass lens to be examined, and for a judgmental opinion of the impact resistance of that lens to be based on the regularity of the observed pattern. Laboratory experiments were carried out to determine the validity of this practice.

Wavelength dependence of birefringence in highly birefringent fibers
Optics Letters, 1982A simple technique is used to measure the wavelength dependence of the birefringence in highly birefringent fibers. In stress-induced fibers, the stress and shape birefringences reinforce each other, whereas in elliptical-core fibers the stress and shape birefringences can either reinforce each other or partially cancel, depending on the wavelength.
