Abstract
A novel Large Shearing Interferometer with four-plate that can adjust shearing distance freely and work in equal optical path is presented. It is used in measuring the pulse laser (from ns to ps) wavefront radius of curvature particularly. The interferometer overcome not the only shortcomings in single and double-plate shearing interferometer, but the diameter of optical plate for the interferometer is only one half or smaller than the beam splitter in three-plate cyclic shearing interferometer. Experiment results indicate that measurement error is smaller than plus or minus 5%(R: 30 to approximately 1000 meters). It also can be used in measuring the focal length and wavefront aberrations of optics.
