摘要Blazed grating, as one of the gratings, is widely used in liquid crystal phased array with beam deflection. Based on the wave control method of blazed grating model, the relationship between the beam deflection angle and the grating constant are deduced. The construction of liquid crystal phased array blazed grating model based on diffraction intensity changes with the derivation of secondary phase modulation, simulation results show that with the normalized phase difference between electrode increased, the original zeroth main diffraction will be all transferred to the first main pole, to achieve the transfer of light energy and the beam deflection.
