Abstract
An A liquid-crystal adaptive optics actuator comprising a two-dimensional array of pixels (), wherein each pixel () is connected to a control circuit by means of a control line signal path () that comprises an electrical interconnection () and a meandering resistor (), 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.
