本文采用三双曝光全息干涉测量系统，对一定温度下磁盘机底座的弯曲热变形场进行了测试，获得了底座内外表面因温差的存在所产生的热变形条纹图，分析比较了不同温差下的变形量大小。
In this paper, three double exposure holographic interferometry system was used to test the bending deformation field of the disk drive base at a certain temperature. The thermal deformation fringe patterns of the inner and outer surfaces of the base due to the temperature difference were obtained. Deformation size.
