Lightweight, Thin and High-Performance Polarization Modulator for Varifocal Liquid-Crystal Lens System
Description:
To realize a varifocal lens for head mounted displays (HMDs), we have fabricated a single liquid crystal switchable half wave retarder using dual frequency liquid crystals. This switchable half wave retarder has shown high modulation efficiency comparable to that of conventional switchable half wave retarders. In addition, our switchable half wave retarder exhibits very high transmittance with a broad wavelength range.
