研制了偏振多通道相机，并采用该相机进行激光散斑照相，对高温动态热形变场进行了研测，拍摄一张散斑图可得到物体在热形变过程中各瞬志热形变场的二维信息。通过滤波技术可再现各瞬时热形变场的分布情况及其变化情况。
Polarimetric multi-channel camera was developed and the laser speckle photography was used to study the dynamic thermal deformation field at high temperature. A speckle pattern was taken to obtain the thermal deformation field of each instantaneous thermal deformation object Dimensional information. Through the filtering technology can reproduce the instantaneous thermal deformation field distribution and changes.
