Abstract
The Mobile Modular Display for Advanced Research and Training (M2DART) was designed and fabricated at the Air Force Research Laboratory (AFRL) Warfighter Training Research Facility. The M2DART is part of a long term development goal of AFRL to produce a display and imaging system combination with significantly improved visual acuity in a full field-of- view/field-of-regard environment. The M2DART is an eight- channel, state-of-the-art, real image, rear-projection visual display system. It is a full color, high resolution, wraparound display designed for use with single-seat cockpit simulators. Depending on the number of available image generator channels, the system allows for a wide instantaneous field-of-view, when used in conjunction with a magnetic head tracker and video router combination to provide a full field- of-regard. The display is designed to accommodate a variety of visual image generators and cockpit simulators. The system uses commercial off-the-shelf (COTS) BARCO CRT projectors to display the out-the-window (OTW) visual imagery to the pilot. The M2DART concept demonstrates that a rear-projected, real image approach is a viable means of providing full color imagery to flight simulators with improved brightness and resolution characteristics. The final design of the M2DART represents a balance between such considerations as training requirements, the number of available image generator channels, system resolution, field of view, brightness, image stability and maintainability. This paper will provide a system description, which includes design trade-off considerations, hardware configuration, screen geometry, field of view, and performance specifications.
