Abstract
This chapter discusses the two-dimensional (2-D) and three-dimensional (3-D) information display using optics. Acousto-optic modulators have been used for 2-D displays as well as for 3-D display applications. In modern display applications, there are increased needs for a real-time device for optical information processing; such a device is often called a spatial light modulator (SLM). Devices and systems based on acousto-optic interaction have played and continue to play a major role in various types of optical information processing. While applications involving SLMs are abundant, large high-resolution 2-D displays still present a challenging problem and large 3-D displays with sizable viewing angles remain formidable. This becomes one of the ultimate problems in modern optics, as current SLMs are not suitable for such applications due mainly to their limited spatial resolution and size.
