测量武器射击时的身管振动情况,是一项比较复杂的工作,这主要是因为武器在射击时件随着很剧烈的后座运动。现有的标准测量传感器,都不宜测量复合运动。因此,必须另行选择。一般来说,可供选择的测试方法有高速电影摄影、可变电阻传感器以及本文所要介绍的光学跟踪仪。光学跟踪仪简介光学跟踪仪是一种电子光学位移跟踪装置。达种仪器可跟踪不连续反光或发光的目标,光经过仪器光学系统而聚焦在析象管的光阴极上。光阴极发射的电子数日随着投射光强的改变而改变。这些电子被加速进入一个小孔,经放大而输出同进入电子数目成比例的电流。
The measurement of the tube vibration at the time of the shooting of a weapon is a relatively complicated task, mainly because of the very sharp rear seat motion of the weapon during shooting. Existing standard measurement sensors, are not suitable for measuring composite motion. Therefore, we must choose another. In general, the choice of test methods are high-speed movie photography, variable resistance sensor and the optical tracker to be introduced in this article. Optical Tracker Introduction Optical tracker is an electronic optical displacement tracking device. A variety of instruments can track discrete reflective or luminous target, the light through the instrument optical system and focus on the CRT cathode. Photoelectrons emitted by the photocathode change with the change of projection intensity for several days. These electrons are accelerated into a small hole that is amplified to output a current proportional to the number of incoming electrons.
