摘要
本文给出近场光学相控阵扫描的理论分析及计算 ,并得出结论 :当相控阵单元规则排列并发生近场干涉时 ,相控单元的尺寸可取得比波长长 。
a theoretical calculation formula of regular optical phased array scanning with near field interference are given,and a conclusion is derived that when optical phased array is arrangedin order and interferes in near field,the size of the unit of phase array can longer than the wavelength of used,and there is only a bright spot on the given scanning direction.
