【Abstract】 An optical fiber true-time-delay line with temperature controlled large dynamic range is designed.The temperature distribution and the incremental rate with the temperature change are simulation analyzed.This true-time-delay line has a dynamic range as large as 7.3 ns and has a temperature change range of 40 ℃.The influence of semiconductor coolers,heat sinks,and containers on the dynamic range is studied experimentally,and the dynamic range and incremental rate of the designed delay line are measured,the results are well in accordance with those of the simulation results.更多还原
