摘　　要：研制了一套用于测量超长焦距的泰伯-莫尔干涉仪,并设计了一套校准设备和方法对泰伯-莫尔干涉仪的测量不确定度进行评定,核准焦距范围达100 m。校准设备包括了一套焦距发生器和激光光源,利用经过计量的标准透镜和实验对焦距发生器进行标定、测量和量值溯源。通过实验结果分析和计算,可知该校准技术具有良好的测量不确定度,能够对基于泰伯-莫尔方法的焦距测量系统进行精确校准。Abstract It developed a method to calibrate the foci-meter based on Talbot-Moir6 interferometer, the calibration range of focal length up to 100 meters. Moreover, it introduced a foci-meter based on Talbot-Moire interferometer. It includes a lens group and a laser source to generate laser beams with steady focal length and wavefronts which used to calibrate the foci-meter. The focal length of the lens group is measured by experiments taking advantage of a traceable lens.The following conclusions can be derived from experimental results： the uncertainty of this calibration method is acceptable.
