An Ultra-fine Spatial Light Modulation Device

摘要

Video holography would be a means by which viewers could see stereoscopic images from any viewing position. A practical form of video holography requires a high-definition, high-speed-response spatial light modulator. STRL has been working on an ultrahigh-definition spin injection light modulation element that exploits the magneto-optical Kerr effect, in which the optical polarization-plane changes as the magnetization direction of a magnetic layer changes, and spin injection magnetization reversal, whereby the magnetization direction reverses by changing the direction of an electric current.
