摘要
利用激光可以在非接触、远距离的情况下实现语音信号的探测。激光远距离语音探测技术在侦听、多模监控、入侵检测、搜救、激光麦克风等领域具有广泛的应用前景。从激光远距离测振系统和探测信号的分析处理方法两个方面综述了激光远距离语音探测技术的研究进展,并展望了该技术的未来。
Usually,lasers can be used for speech signal detection in non-contact and long-distance scenarios.Consequently,the remote laser speech detection technology has broad application prospects in laser interception,multimode monitoring,intrusion detection,search and rescue operations,laser microphones,and other fields.In this paper,we review research advances in the remote laser speech signal detection technology from the perspectives of remote laser vibration detection systems and detected signal analysis and processing methods;moreover,we expound the future development prospects of this technology.
