摘要(Abstract)：

在针对油气产品进行太赫兹光谱测试时,仪器自身误差会为测试结果来较大影响,对实验仪器进行误差标定对油气资源的太赫兹表征与精细评价具有重要意义。对油气太赫兹光谱仪进行了误差测试与分析,并对由延迟线的移动速度导致的测试误差进行了标定。结果表明,较小的移动速度有利于减少时域波形在延迟时间与幅值上产生的偏差及浮动,其中4组实验延迟时间的浮动范围分别为0.1Ps、0.1Ps、0.2Ps和0.4Ps;信号幅值的误差率分别为2.26%,1.76%,3.28%及5.82%。此外,在测试过程中,激光器输出功率的变化也是主要的误差来源,在测试时通过实时记录输出功率并根据线性关系进行归一化处理可降低这一误差。
