Paper Abstract

The Litton Soldier Vision Sub-system is a lightweight, low power, display system that can be mounted on the soft cap, helmet or bare head, of a soldier in the field. The head mounting approach allows hands-free operation by the soldier, thereby providing the ability to run stand shoot while still being able to observe the computer's display. Likewise, command post staff, maintenance technicians, even firemen, can function in a similar manner. The system contains four major components: HMD, electronics unit, battery housing, and cables. The HMD is a folded path design using a 60 hertz refresh active matrix liquid crystal display, with backlight from an array of six light-emitting diodes. The typical power source is a nominal 9 VDC lithium battery, the BA-5600, but rechargeable batteries can also be used. Extensive design effort has been expended to add the shielding and filters necessary for unimpaired operation in close proximity to tactical radios. The entire system, including battery and cables, weighs approximately 2.3 pounds. Small size, low power, and light weight allow the system to be used in many varied applications, including display of maintenance manuals, remote medical assistance, and field reconnaissance.
