Hardware Improvements To The Helmet Mounted Projector On The Visual Display Research Tool (VDRT) At The Naval Training Systems Center

The Visual Pisplay Research Tool includes a helmet mounted projector for the display of flight simulation Area-of-Interest imagery on a 10 foot radius dome. The imagery is transmitted to the helmet using two coherent fibre optic ribbons. Some improvements have been made to the fibre optic system and to the helmet fit. The imagery is head and eye slaved and the concepts for image positioning and stabilisation are described.
