Real time 3D display with acousto-optical deflectors

Abstract

A laser volumetric display system based on the sequential scanning of two-dimensional images on a rotating diffusing screen is introduced. The system can generate volume images having a dimension of 120 × 120 × 100 mm3 with 250,000 resolvable volume pixels. The images are displayed with the frame rate of 15 to 25Hz. The distance between the projection objective and the screen is 3m. The volumetric images generated by the system are clear and sharp.
