Paper Abstract

The image from LD recording system with stripes is a very common phenomenon. The defects made the images blur and inseparable the gray scales. The article gives the principle and lots of actors generating stripes. Through careful analyses and discussion, the main cause of stripes is the optical system. Especially, the LD laser beam's uniformity that is inner the light aperture and the position of the light aperture's real image exerted a tremendous influence on stripes. Then, the article gives lots of methods to solve the problem. From mechanical structure to optical system, we discuss the components thoroughly. The uniform laser beam passes through the light aperture and fills it completely. The theoretical formula gives out the position change of the light aperture's real image. When we put these methods into action, the stripes almost disappear. In objective reality, the images meet the use.
