Measurement of 2-D Instantaneous Vibration Mode Shapes with a Polarized Multichannel
偏振多通道相机 激光散斑 二维瞬态振型 polarized multichannel camera laser speckle 2-D instantaneous vibration mode shapes
摘要
利用偏振多通道相机进行激光散射照相,研测振动物体的二维瞬态振型.拍摄一张散斑底片可同时记录振动物体在各不同位相下的一连串二维瞬态振型的全场分布信息.
Abstract
A polarized multichannel camera used for measuring of 2-D instantaneous vibration mode shapes is presented. The whole-field information of 2-D instantaneous vibration mode shapes at all phases of a vibration object can be recorded simultaneously on one specklegram in one step.
