CCD diffused transmission imaging method is used to measure laser intensity distribution and power. The measurement principle of the design is presented. The designed system’s configuration is summarized. There are particular introduction for each part of the system. The scattering properties of the diffusion screen is researched through experiment. There is highlighting information on the design of optical system, light path, reflector, focal length and aperture of camera lens, and depth of field of CCD camera are respectively introduced. The data processing software are introduced. The design implements large laser spot intensity distribution measurement and power measurement in small space at the same time, it has the advantages of high resolution(5 mm) for intensity distribution measu
