【Abstract】 Based on Fraunhofer diffraction theory and Fourier optics theory,wave control principle of liquid crystal optical phased array in the situation is derived when Duty cycle is equal to 1. On the basis of the blazed grating modulation idea,a new method to analysis the problem of the sidelobe in the liquid crystal optical phased array is proposed and the distribution of the outgoing phase of the liquid crystal optical phased array is adjusted to achieve sidelobe suppression.更多还原
