Abstract
A natural 3D image can be generated by projecting massive 2D images. A number of afocal and telecentric imaging systems are aligned in a modified 2D array and are multiplexed to project a number of 2D images into different horizontal directions. Such multiple imaging system has large aberration. The combination of lenses is used to reduce the aberration of a Fresnel lens which is used as a common lens of the multiple imaging system. Electronic correction is also used to reduce the image distortion. These two methods greatly improve the 3D image quality.
