【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。更多还原

【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.更多还原
