Abstract : An articulated light guide having internal mirrors and rotatable joints, provides a transmission path to a helmet mounted projector wherefrom light is transmitted onto a retroreflective screen to produce images utilized in simulation training. Located at the screen are photodiodes which detect the orientation of said images with respect to a reference and provide alignment signals to a servo-controlled image rotation device. (Author)
