Polarization analysis apparatus for evaluating the depolarization effect

摘要

PROBLEM TO BE SOLVED: To evaluate easily and quantitatively the degree of a depolarization effect of a film having a depolarization function.;SOLUTION: A polarization analyzer comprises: an irradiation optical system for irradiating a measurement object disposed at a predetermined position with linearly polarized light; a light-receiving optical system disposed at a position where a transmitted light from the measurement object is received; a rotatable analyzer configured around an optical axis of the light-receiving optical system and disposed between the measurement object and the light-receiving optical system on the optical axis; a two-dimensional light- receiving element disposed at a position where transmitted light passing through the analyzer is received through the light-receiving optical system; a calculation processing unit 10 for capturing detection light intensity in each pixel of the two-dimensional light-receiving element for a plurality of rotation angles when the analyzer is rotated and for calculating polarization properties of the transmitted light from a plurality of positions of the measurement object; and a display 11 for displaying, on the Poincare sphere, the polarization properties of the transmitted light from a plurality of positions of the measurement object calculated by the calculation processing unit 10.;COPYRIGHT: (C)2014,JPO&INPIT
