Precision analysis on the phase delay measurement method of Fourier quarter-wave-plate on liquid crystal optical phased array
摘要
Abstract
With the purpose of highly precise measuring the phase delay distribution of liquid crystal optical phased array,the accuracy and precision of the measuring method of Fourier Quarter-Plate are both analyzed theoretically and evaluated experimentally.Numerical simulations indicate that the error of this method is smaller than 0.3°when we assumed a couple of ordinary parameters on the system.A practical experiment on a standard half wave plate is also accomplished showing that the accuracy is smaller than 0.3°and the repeat precision is also smaller than 0.3°.Simulations and experiments show a good agreement with each other so that a demonstration Fourier Quarter-Plate method can meet the requirement on phase delay measurement better than 0.5°on liquid crystal optical phased array.关键词
