Abstract

Lens-array based imaging system is a kind of the direct-view system that is currently a hot topic of research. In fact, the viewing parameters of this system have been one of the focuses of research since its invention. However, most current literature discussions are based on depth of field, spatial resolution, and field of view. Only a few documents or products use angular resolution, spatial resolution, and field of view as criteria. The angle resolution is one of the parameters in the human eye vision module. This article will try to discuss the hardware conditions for realizing the angular resolution in the LCD discrete pixel system and its influence on the 3D perception. The results show that the angular resolution is determined by the number of pixels in each sub-image and is proportional to the number of elemental images and is limited by the LCD pixel pitch.
