Title:
TRANSMISSION AXIS MEASURING SYSTEM USING NON-NORMAL ARRANGEMENT OF POLARIZER
Document Type and Number:
WIPO Patent Application WO/2018/105946
Kind Code:
A1
Abstract:
A transmission axis measuring system using a non-normal arrangement of a polarizer according to the present invention comprises: a light source for emitting incident light in one direction; a polarizer in which the horizontal angle (ε) and the vertical angle (η) of the incident light emitted from the light source are changed; an angle adjustment mechanism for controlling the change in the horizontal angle (ε) and the vertical angle (η) of the polarizer; a polarimeter that is non-normally arranged with the polarizer; a focusing lens for focusing polarized incident light transmitted through the polarimeter; a photodetector, located on an optical axis opposite to the focusing lens, for measuring the amount of the incident light passing through the focusing lens; and a transmission axis calculation module for calculating a transmission axis (θ) according to the amount of the light measured by the photodetector. Accordingly, the present invention has the effect that it is possible to quickly and accurately measure the transmission axis of the polarizer by reflecting errors generated in a setup process for measurement of the transmission axis through an induced relationship. Also, the present invention has the remarkable effect that it is possible to utilize an enhanced polarization resolution and broadly apply the same to transmission and storage of signals, encryption of information, etc., by generating various polarized signals by means of the same polarizer by using an intentional non-normal arrangement of a polarizer.
