FTIR提供了三种时间历程测量方法:间隔测量、快速扫描和步进扫描测量;时间分辨率分别为1秒、50毫秒、5毫秒(可选:10纳秒)。在这里,我们将回顾每种方法的基本特征和测量方法。每种方法对干涉仪中的移动反射镜使用不同类型的扫描方法。“间隔测量”是通过定期扫描执行的,“快速扫描测量”使用移动反射镜的更快扫描速率。使用“步进扫描测量”,移动反射镜在每个数据采样点停止,并在每个点受到干扰。Application Note280-SO-0007 Time Course Measurementwith FTIR2/2Application Note FTIR offer three met h od s for time course measu r ement : i n terva l measureme n t, r a p id-scan, and ste p -sca n ; t he t ime r esol uti on i s 1sec, 50 msec, 5 msec (opt i onal : 10 nsec) respectively.
