摘要
本文介绍了一种新型的双纵模双频激光干涉仪,由于采用热稳频,延迟线移相等关键技术,使得干涉仪具有结构简单,成本低廉,动态性能好,精度高等特点.
In the paper,a new twin longitudiat two frepuency laser interferometer system is analysed,Using thermal frepuency-stabilizing,phase-delaying wire and other new techniques,which is cheap and simple in structure and has wide dynamic range.
