The Computer Generated Hologram（CGH）technique is the main method for optical testing the free form surface .For testing a convex free form surface mirror, a CGH element with the surface testing, interferometer and free form mirror precise position function was designed by use of appropriative software, the testing precision was less than 0.011λ（λ=632.8nm）in RMS value by this means.
