S. Denicola et al., WAVELENGTH DEPENDENCE OF THE PHASE RETARDATION OF A QUARTER-WAVE PLATE, Applied physics. B, Lasers and optics, 60(4), 1995, pp. 405-407
We describe an optical heterodyne polarization interferometer that can
be efficiently used for the precision measurement of the change in th
e state of polarization of a light wave induced by polarizing optical
devices. This technique is used to measure the change with wavelength
of the phase retardation of a quarter-wave plate. A theoretical deriva
tion is presented to permit computation of the wavelength dependence o
f the phase shift induced by a quarter-wave plate.
