摘　　要：为了扩大观察范围,模块化结构单元,提高可靠性,设计了一款多功能周视镜。利用滚珠丝杠和直线轴承实现头部升降,扩大产品的观察范围;利用齿轮组差动技术实现上反射镜运动传输,保证系统可靠性;利用步进电机驱动道威棱镜及配合绝对值式光电编码器反馈角值位置信息,消除周视过程中的图像旋转,保证系统观瞄和测角精度。实验结果表明:周视镜可昼夜观瞄、昼间3×~6×连续变焦、头部升降300mm、方位向全周视、测角精度在连续转动下不低于±1mard。In order to enlarge the observation range,adopt the module units and raise the reliability,a multi-functional panoramic sight was designed.By using ballscrew and linear bearing,the lifting at its head was realized so that the observation range of the product could be enlarged.By using gear cluster differential technology,the moving transmission of the mirror was realized so as to guarantee the system reliability.Through driving the Dove prism with a step motor and the cooperation with the absolute value type photoelectric encoder to feedback the angular value position information,the image revolving during panoramic sighting was eliminated,so that the system observation and aiming accuracy and the angle-measuring accuracy could be guaranteed.Engineering practice shows that the panoramic sight can perform the following actions:observation &aiming day and night,zooming continuously 3×~6×at day,300 mm lifting at its head,all panoramic sighting in azimuth,the angle-measuring accuracy is no less than ±1mard during continuous rotation.
