Abstract
A tunable liquid crystal optical device is described. The optical device has an electrode arrangement associated with a liquid crystal cell and includes a hole patterned electrode, wherein control of the liquid crystal cell depends on electrical characteristics of liquid crystal optical device layers. The optical device further has a circuit for measuring said electrical characteristics of the liquid crystal optical device layers, and a drive signal circuit having at least one parameter adjusted as a function of the measured electrical characteristics. The drive signal circuit generates a control signal for the electrode arrangement.
