Automatic measurement of the Stokes vector of light.

摘要: A system which measures the Stokes parameters of light automatically over a wide range wavelengths is described. The method requires two piezooptic modulators, three lock-in amplifiers, and an on-line minicomputer for data processing. absence static retardation plate provides unprecedented insensitivity to beam wandering. Typical performance such as response time, accuracy, detectivity function incident polarization are given.
