摘　　要：提出了一种基于偏振激光干涉技术的波长计，该波长计能在微米行程上实现10^-6的测量精度，位移行程的缩减有效地减小了环境温度、波长漂移、空气折射率对测量精度的影响。给出了两种未知激光源（DL100-Toptica和Nd：YAG）的波长测量值及不确定度值，同时还给出了该波长计与商用波长计的比对结果。A new type of laser wavemeter based on polarimetric interferometer is proposed. This wavemeter can achieve the accuracy of 10-6 on micrometric range. This wavemeter is less sensitive to environmental temperature, wavelength shift, and index of air with reduced displacement range. The experimental results of measured value and uncertainty for two unknown laser sources （DLIO0 -Toptica and Nd：YAG） are presented. The experimental comparisons between our own -developed wavemeter and a commercial wavemeter are also described.
