Hj. King et al., OPTICAL HETERODYNE POLARIMETER FOR MEASURING THE CHIRAL PARAMETER ANDTHE CIRCULAR REFRACTION INDEXES OF OPTICAL-ACTIVITY, Optics letters, 18(22), 1993, pp. 1970-1972
A double-loop optical heterodyne polarized interferometer is set up to
measure the optical rotation power and the circular refraction indice
s of optical activity. The system accuracy in the measurement of both
the rotation angle and the chiral parameter is 10(-4) within the +/-2-
degrees phase detection sensitivity of the system. The circular refrac
tion indices of quartz activity were successfully demonstrated.
