POLARIZATION DISPERSION MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To measure the polarization dispersion of a subject with excellent precision by using the Jones matrix analysis method. SOLUTION: The polarization dispersion measurement device comprises: a light frequency com generation part for generating the light frequency com composed of≥n light frequency components with light frequency interval f; a polarization wave controller for controlling the state of the polarization and inputting the polarization into the subject; a demultiplexor for demultiplexing n light frequency components from the light frequency com transmitted through the subject; n polarimeters for measuring the polarization state of each frequency component demultiplexed by the demultiplexor; a measurement device controller for setting independent 3 polarization state on the Poincare sphere to the polarization controller; an operation part for calculating the polarization dispersion value of the subject by the operation of the Jones matrix of the subject from the relation between the input polarization state set by the polarization controller by the measurement device control part, and polarization state of each light frequency component measured by each polarimeter.
