COMPACT DEVICE FOR SEPARATE VISUALIZATION OF PERIPHERAL VISION REGION AND CLEAR VISION REGION IN TRAINING SET Russian patent published in 2000 - IPC

FIELD: design of training sets, in particular, drive simulators. SUBSTANCE: goal of invention is achieved by introduced two monochrome liquid-crystal matrices, which are embedded in helmet indicator and use fiber-optical disks as external cover glasses. Outer surface of fiber-optical disks is shaped as spherical segment and provides possibility of diffuse light diffraction. In addition device has two light guides, each of which has red, green and blue light-emitting diodes, which are connected to respective outputs of video signal generation units. Also, device has two concave spherical mirrors, which are located with respect to fiber-optical disks, so that focal surfaces of mirrors coincide with outer spherical surfaces of disks. This produces mirror DUOVID collimator for each of user's eyes. Light guides with light-emitting diodes are located in close proximity to respective liquid-crystal matrices on side which is opposite to fiber-optical disk. Flat units for playing first images are located in close proximity to windings of training set cab. EFFECT: increased functional capabilities. 3 dwg
