The Naval Training Equipment Center (NAVTRAEQUIPCEN) is in the process of developing a large screen laser display system for training. This system incorporates several novel concepts and components, some of which were developed at NAVTRAEQUIPCEN and others that were developed in industry. The display area is a 3 meter radius spherical screen with a laser display coverage of 360° horizontally and 60° vertically. The display pickup is a probe over a model board. The image transfer system from the probe to the projection lens makes use of 12 linear charge coupled device arrays, each one constituting one channel of video data. A novel concept involving channel interlace of the twelve channels produces a continuous, seamless laser display with no problems such as color matching, edge matching or brightness matching that arise in multiple discrete channel display systems. The purpose of this paper is to briefly describe the system and then report on the design, fabrication and testing of the major subsystems. The subsystems that will be reviewed are the laser scanner, the prism rotators, the projection lens and the electronic synchronization of the systems.
