Paper Abstract

An instrumental device for complete, accurate, fast and simultaneous measurement of all parameters of quasi-mono-chromatic light: wavelenth, intensity, degree and state of polarization is presented. The performance of the device is based on a new principle which makes use of a polarization holographic grating. The measured light is split into four beams of intensities I , 12 , 13 and 14 . To determine the four Stokes parameters, these intensities are measured simultaneously by four photocietectors and the electric signals are processed by a microcomputer. At the output of the device all the four Stokes parameters are given as well as the ratio of the polarization ellipse axes and its azimouth. The use of linear ray detector for measurement of 13 and 14 intensities makes it possible the evaluation of light wavelenth through analysis of light beams angle of diffraction.
