Abstract

The performance of an electro-holographic display has been limited by space and spatial bandwidth of spatial light modulators. This paper presents a new type 3D display using numerous small-size light sources. The concept of the display is based on the electro- holographic display using acousto-optic devices. Each light source is aligned on a circle at narrow intervals, and its output beam is focused on the center of the circle. Its focal point or the image of its focal point is scanned by the mechanical X-Y scanner, and each light's intensity is modulated by each parallax image of the viewing angle. This display can produce big-and-natural 3D images with high resolution and high refresh-rate.
