摘　　要：基于地雷独特机械特性和声-地震耦合原理的声-地震耦合探雷技术,在埋设地雷的安全有效探测方面具有广阔的应用前景,但针对实用工程探雷系统的研究还需要做大量工作。其中,声波耦合的地表振动信号非常微弱复杂,如何对其进行精确快速测量是一个关键难题。本文在声-地震耦合探雷技术原理的基础上,对地表振动的非接触激光测量技术(包括激光多普勒干涉技术、电子散斑干涉技术和激光自混合干涉技术)进行综述分析,并分析了电子剪切散斑干涉技术用于声-地震耦合探雷的可行性。Acoustic-to-seismic coupling landmine detection technology based on the unique mechanical characteristics of landmines and the acoustic-to-seismic coupling principle has broad application prospects in safe and effective detection of landmines.However,a significant amount of work must be done to study the practical landmine detection system.Among them,the acoustic coupled surface vibration signals are very weak and complicated,which has always been a challenging problem to detect such signals accurately and quickly.In this paper,the non-contact laser measurement techniques of surface vibrations based on the principle of the acoustic-to-seismic coupling landmine detection technology were reviewed,including laser Doppler interferometry,electronic speckle pattern interferometry and laser self-mixing interferometry,etc.,and the application feasibility of electronic speckle-shearing pattern interferometry in acoustic-to-seismic coupling landmine detection was analyzed.
