摘要/Abstract

摘要： 以氦氖激光为光源，利用球面波会聚光的干涉，实验测量比累对切透镜切去部分的宽度，并对该宽度值进行不确定分析;以其宽度值作为已知量，分别利用平面波发散光的干涉和球面波会聚光的干涉两种干涉方法，测量钠

　　光波长，并用实验数据分析结果，验证实验测量比累对切透镜切去部分宽度的合理性.

Abstract: The interferometry of spherical wave convergent light is used in this paper to

experimentally measure the width of the cut- off part of the Billet split lens by using He-

Ne laser as the light source，and the uncertainty

analysis of the width value is carried out.Also，the width value is taken as a known

quantity to obtain the length of the sodium light wave based on the interferometry of plane wave divergent light and spherical wave

convergent light.The experimental data are analyzed to verify the rationality of experimentally measuring the

width of the cut-off part of the Billet split lens.

Key words: split-wavefront, double-beam interferometry experiment, Billet split lens, width of the cut-off part
