基于计算机控制的自行火炮测瞄装置MTF测量

Measurement of Measuring-sight device of self-propelled Gun MTF Base on Computer Control

测瞄装置是自行火炮的重要组成部分。本文介绍了一种采用光电探测原理和计算机控制的信息处理技术，对自行火炮测瞄装置调制传递函数（MTF）进行测量的方法；本文提出的计算机对自行火炮测瞄装置MTF的测量，突破了机械扫描法模拟傅里叶变换原理，采用蓝牙技术和计算机控制的光电探测原理完成对测瞄装置MTF的测量。用该方法全面评价测瞄装置质量，具有操作简单、速度快、精度高、测量周期短的特点，适用于较小空间的自行火炮对测瞄装置进行MTF测量。

Measuring-sight device is one of the important parts of the self-propelled gun.In this article,a method which has taken advantage of the information processing technology of photo detection and compu(?)er controlling is introduced,and it can be used to measure the modulation transfer function (MTF) of the measuring-sight device.This method has the charaters of easy operation,high speed and short measuring period,and can be utilized in measuring MTF of the measuring-sight device of the self-propelled gun.
