Paper Abstract

We propose a method to increase the viewing resolution of an autostereoscopic display without increasing the density of microlenses. Multiple projectors are used for the projection images to be focused and overlaid on a common plane in the air behind the microlens array. The multiple overlaid projection images yield multiple light spots inside the region of each elemental lenslet of the microlens array. This feature provides scalable high resolution images by increasing the number of projectors.
