Abstract

A projection apparatus for holographic stereogram recording has a transmissive liquid crystal device and a diffusion screen. The transmissive liquid crystal device has a microlens array on its incident side and a polarizing sheet on its transmitting side. The microlenses are in one to one correspondence with the pixels of the liquid crystal device. The position of the diffusion screen is chosen such that the image transmitted to it from the liquid crystal device appears continuous.
