摘要: 飞行训练模拟器广角无限显示系统是飞行训练模拟器的重要组成部分,其设计质量直接影响到飞行模拟器的性能.而广角无限显示系统中准直镜和背投屏的面形是决定广角无限显示系统成像质量的关键因素,因此,准直镜和背投屏的设计成为研制广角无限显示系统的关键.针对设计适用于双座飞机飞行模拟的广角无限显示系统的技术要求,讨论了零视场消像散条件,选取可保证零视场像散为零的镯形面作为准直反射镜的面形,确定了准直镜的尺寸;以弥散斑最小为原则,通过反向光线追迹得到了背投屏的面形和位置,最后进行了准直精度计算.设计的广角无限显示系统可达到水平视场180°,垂直视场45°,已用于飞行训练.

Abstract: Wide-angle infinity display equipment (WIDE) is an important part of airplane simulator which directly affects the performance of airplane simulator. Surface shape of collimating mirror and back-projection screen in WIDE is a key factor which decides imaging quality. Therefore, the design of collimating mirror and back-projection screen turns into a key problem in WIDE development. Aiming at the technical requirement of WIDE of airplane simulator for two-seater airplanes, the condition of compensating astigmation of zero field of view was discussed, the surface of collimating mirror was designed to be bracelet form to ensure the astigmation of zero field of view would be zero, and determine the size of collimating mirror. On the principle for minimum disc of confusion, shape and location of back-projection screen was obtained by inverse ray tracing, finally the collimation precision calculated. The WIDE designed could provide 180 horizontal field angle and 45 vertical field angle, and is already used in flight training.
