Abstract: A transmissive liquid crystal (LC) control structure comprising: a superstrate (44) having a first surface (44a) having a GaN HEMT structure disposed thereon to provide a conductor on the first surface of said superstrate; a substrate (42) having a first surface disposed over and spaced apart from the first surface of said superstrate and having a GaN HEMT structure (43) disposed thereon to provide a conductor on the first surface of said substrate and wherein the GaN HEMT structure on one of the superstrate and substrate surfaces are patterned into individual electrodes; a polymer network liquid crystal (PNLC) (48) disposed in the space between the first surface of said superstrate and the first surface of said substrate; and a control circuit coupled to the individual electrodes.

Abstract: An A liquid-crystal adaptive optics actuator comprising a two-dimensional array of pixels (14), wherein each pixel (14) is connected to a control circuit by means of a control line signal path (16, 20) that comprises an electrical interconnection (16) and a meandering resistor (20), each resistor having a resistance value selected to equalize the RC time constant of each control line signal path associated to each pixel. Each control line is thus capable of carrying one or more control signals and the control line signal path is configured such that all the pixels respond to the control signals with a uniform response time.
