Abstract

Influence of in-plane only retardation switching of an SSD (Smectic Single Domain) liquid crystal both on light diffraction efficiency and beam steering performance has been investigated. An SSD liquid crystal’s in-plane only retardation switching keeping its molecular director always perpendicular to the externally applied electric field is reasonably assumed to provide unique performance both on light diffraction and beam steering. The in-plane only retardation switching was confirmed with polarimetry and light throughput dynamic profiles both for linearly and circularly polarized incident beams. Using the SSD liquid crystal, < 1 ms response with up to 6 degrees steering has been confirmed.
