摘要：
Methods of laser interferometry based on the optical feedback and frequency-modulated laser diode effects are described. An interference signal is analyzed for problems concerned with range finding, displacement estimation, and measurement of velocities and vibration parameters. Relationships between the object movement characteristics and the interference signal parameters are found. Advantages of the new trend in interferometry are an extremely high sensitivity to scattered light, the possibility of estimating the displacement direction and obtaining information from small object surface areas, simple design, and low cost of the interferometers.
