Title:
SYSTEM AND METHOD FOR DETECTING SURFACE VIBRATIONS
Document Type and Number:
WIPO Patent Application WO/2016/103271
Kind Code:
A3
Abstract:
A system for detecting vibrations from a surface is provided. The system includes a coherent light source for projecting a multi-beam pattern onto the surface and an imaging device for mapping a speckle field generated by each spot formed on the surface by the multi-beam pattern to a unique region of an imaging sensor. The system further includes a processor for processing speckle field information received by the imaging sensor and deriving surface vibration information.
