Abstract: Based on the basic theories of holography, the conditions of occurrence of holographic real image are analyzed. The scheme that the holographic real image is shot and reconstructed with normal and collimated laser beam is put forward. The experimental results suggest that the qualities of the holographic real image can be im- proved by using normal and collimated laser beam for shoot and reconstruction. In addition, the holographic real image is displayed in different scattering media, respectively, and the one meeting requirement is determined.

Key words: holography, real image, shoot and reconstruction
