偏振扫描相机测量二维动态热形变场
Dynamic Measurement of 2-D Thermal Deformation Fields with a Polarized Scanning Camera
摘要
提出了利用偏振扫描相机进行激光散斑照相, 研测了物体的二维热形变场。全部动态过程的信息可记录在同一张散斑图上, 且在全场滤波时可连续再现热形变物体的二维变形信息。
Abstract
A polarized scanning camera used for dynamic measurement of thermal deformation fields is proposed. The whole dynamic thermal deformation information of an object can be recorded simultaneously on a specklegram in one step, and reappeared continuously during whole field filtering.
