Abstract

Based on birefringence laser frequency splitting principle.This paper introduced the experimental system for static and dynamic measurements.The static measurements include the angle detection with 0.3″ angle precision and the displacement detection with 10nm resolution.The dynamic detection can be utilize for detecting of the vibration frequency and amplitude with 15nm resolution at the range of 0.1 Hz～8kHz.The method has many advantages:higher sensitivity,wide frequency response range and good linearity.
