Dynamic Dual-Frequency Control of Nematic Liquid Crystals in Adaptive Optics Systems.

Abstract

This report results from a contract tasking Laser Measuring Branch, P. N. Lebedev Physical Institute, Samara Branch as follows: The contractor will investigate dual-frequency control of liquid crystals in order to establish limits on rise and fall times as outlined in the proposal. He will also investigate control methods for liquid crystal modulators. The contractor will design and construct a programmable generator that he will use to study the possibility of improving the response time of liquid crystal modulators by controlling the voltage time history.
