Abstract

A simple laser projection system for small images using a piezoelectric scanner is described. The image is ~50 mrad and can be controlled by a computer in real time. The 2-D image is formed by a single piezoelectric scanner. Being completely solid-state, the scanner is mechanically stable, rugged, and has a usable resolution up to 100 × 100 pixels at visible wavelengths. The image can be generated and controlled by a personal computer, thus making this system portable. Because of the small divergence of the image, this system can be incorporated into a large x-y deflection system through which the small image can be directed to any position on a large screen. The deflection system, the driving electronics, and experimental results are discussed and shown.
