摘要

一种改进形式的激光直接写入已应用于相位补偿反射阵列相关器(RAC)。利用激光定向刻写精确的空间校正图，对YZ铌酸锂材料上制作的3600 TB(时间带宽)RAC延迟线的相位响应特性进行了修正。得到的时间副瓣被抑制到-44 dB。

Improved time-sidelobe performance in SAW RAC's using laser aided phase compensation

A modified form of laser direct writing has been applied to phase compensate reflecting array correlators (RAC). Accurate spatial correction patterns were written by directed laser light, trimming the phase response characteristics of a 3600 TB (time-bandwidth) RAC delay line fabricated on YZ lithium niobate. The resulting time sidelobes were suppressed to -44 dB.<>
