Portable three-dimensional display system for CGHs

摘要

A computer generated hologram (CGH) requires a high-resolution device to represent a hologram data. I propose a new three-dimensional display method that has the expanded viewing zone and a large object size with a low-resolution device. Using the method, I developed a portable three-dimensional display system that shows 3D objects in the area of 4 × 2 cm. The display showed three-dimensional images which were full parallax, autostereoscopic and viewed binocularly. It is small and lightweight enough to carry by a hand. Moreover, it is assembled at a low cost and uses a low-price transparency sheet with 4000dpi.
