摘　　要：针对当前对脉冲激光波面半径测量缺乏有效的测试方法，提出了集大错位与等光程于一体的四平板剪切干涉法，达到对脉冲激光波面半径的高精度测量。Ｒ值在３０～１０００ｍ的范围内，测量误差小于±５％A novel four plate shearing interferometer that can adjust shearing distance freely and work in equal optical path is presented. It is used in measuring the laser wavefront radius of curvature particularly and the interferometric measurement error is smaller than ±5%(R:30～1000 meters). It also can be used in measuring the focal length of optics.
