作者利用了电阻应变计作为传感器，直接把操纵器的操纵杆的位移量转换为对电影经纬仪俯仰和方位实行跟踪控制的模拟电量，研制成功了一种新颖的单杆操纵器。本文论述了其原理、设计及特点。
Using the strain gauge as a sensor, the author directly converts the displacement of the joystick into an analog electric power that tracks and controls the pitch and azimuth of the film theodolite. A novel single-rod manipulator was successfully developed. This article discusses its principles, design and features.
