Abstract

We present a multiple-input, single-output, weakly nonlinear model of a liquid crystal light valve using a second-order Volterra series and describe an experimental method to measure the nonlinear transfer functions using sinusoidal perturbation and synchronous detection with a lock-in amplifier. Experimentally measured and estimated nonlinear transfer functions are presented. We next discuss the response of the liquid crystal light valve to random inputs and present experimental noise measurements.
