摘要
Abstract
This paper reviews the development of a new configuration of interferometry,Self-mixing Interferometry（SMI）.SMI is attractive because it doesn＇t require any optical part external to the laser and can be employed in a variety of measurements,ranging from the traditional measurements related to optical path length like displacements,small-amplitude vibrations,velocity;to sensing of weak optical echoes,like return loss and isolation factor measurements;and also to a special feature for the interaction with the medium,measurements of physical parameters,like laser line width,coherence length,and the alfa factor.Because it is also a coherent detection scheme,the SMI operation is close to the quantum limit of received field and the minimum detectable amplitudes of 20 pm /（Hz）～（1/2） or better are currently achieved upon operation on diffusive targets,whereas a corner cube allows half-wavelength counting mode or 0.5 μm resolution on a dynamic range up to 2 m.SMI has a compact setup,and is easy to deploy in the field and can interface a variety of experiments from MEMS testing to rotating machine vibration testing to pickup of biological motility as described in the paper.关键词
