为提高基于渐开线原理的快速光学延迟线(FODL)装置的扫描频率和延迟时间,提出一种具有高速及高稳定性特点的光学延迟线装置,分析了延迟线装置装配误差引起的出射光束角度偏转和光程差变化。通过迈克耳孙干涉系统验证装置的扫描频率、延迟时间、延迟平稳性和延迟线性度四个方面的特性。实验结果表明,延迟线装置的装配精度较高,可实现高速高稳定性扫描和较大的光学延迟,其扫描频率为100 Hz,延迟时间为167.45ps,延迟距离为50.06mm,平稳性误差为0.25%,线性度误差为0.05%。
In order to enhance the scanning frequency and delay time of the fast optical delay line （FODL） device based on the principle of involutes, an optical delay line device with high speed and high stability is proposed. The angle deflection and optical path difference change of emergent light caused by the assembly error of the delay line device is analyzed. The characteristics of the device including the scanning frequency, delay time, delay stability and delay linearity are tested with the Michelson interference system. The experimental results show that the delay line device possesses high assembly accuracy and can realize high-speed and high-stability scanning and large optical delay, with the scanning frequency of 100 Hz, the delay time of 167.45 ps, the delay distance of 50.06 mm, the stability error of 0.25%, and the linearity error of 0.05%.
