Simulation and Implementation of Helmet Mounted Sight

Aiming to the engineering requirement of simulating a helmet mounted sight, the angles between the helmet mounted sight and the plane coordinate system are measured by head position tracking sensor in quaternion method. Then they are transformed to Euler angles and sent to computer control modules by shared memory. Integrated with digital control circuit, the display system functions of helmet mounted sight glasses are realized by using the raster and the half transparent and half catoptric prism. The computer control system are used to implement logic control and simulation management, then the simulation to the helmet mounted sight is successfully implemented. The simulation system can meet the demands of simulation training.
