Abstract

We investigate displacement measurements of up to 17 μm on a heterodyne laser interferometer laboratory model. The measurement error for small (up to 200 nm) linear displacements is found to be 270 pm at a 10-s averaging time. The results obtained can be used for developing a space laser interferometric system for the global Earth’s gravity field mapping.

用于空间重力测量项目开发的外差激光干涉仪实验室模型的特性

我们研究了在外差激光干涉仪实验室模型上高达17 μm的位移测量。在10秒的平均时间内，小(200nm)线性位移的测量误差为270pm。所得结果可用于研制用于全球地球重力场测绘的空间激光干涉系统。
