HIGH-SPEED POLARIZATION DEVICE, HIGH-SPEED BIREFRINGENCE MEASURING DEVICE USING THE SAME AND STEREOSCOPIC IMAGE DISPLAY DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a high-speed polarization device capable of switching a polarization state at high speed, a polarization measuring device capable of performing measurement work of the polarization state at a high speed, and to provide a display device capable of changing by switching contents of display images at a high speed. PSOLUTION: The high-speed polarization device 150 for continuously generating different light of the polarization state comprises a plurality of polarization light radiation units 15, each having a polarizer 13 setting a light source 11 and a polarization direction of light from the light source 11 in a specific direction, respectively; a rotating reflective body 17 for outputting the reflected light in a prescribed direction by receiving emission light from the plurality of the polarization light irradiation units 15 by being rotated; and an analyzer 19 for setting the polarization direction of the reflected light on the way of an optical path of the reflected light from the rotating reflective body 17 in a fixed direction. The polarization light radiation unit 15 comprises a first compensator 27, arranged on a circular arc with the center at the rotating reflective body 17 and compensating for the changes in the polarization state due to the rotating reflective body 17.
