A new type of ultrasonically controlled concave liquid crystal lens based on traveling waves (TWs) with a divided electrode structure and an appropriate driving scheme is proposed. The lens uses an annular piezoelectric ceramic that is divided into four parts for four-phase driving and consists of a liquid crystal layer in a sandwich structure between two circular glass substrates. The lens configuration was simulated by finite element analysis using Ansys software. In this work, we discuss the use of TWs to expand the lens aperture and clarify the lens’ optical characteristics using a Shack-Hartmann wavefront sensor. |
