光电信息测量瞬时速度的研究

The Study on the Photoetetric Information Measures Instantaneous Velocity

在科学研究和工业生产中,常常需要精确测量各种物理参量。如:重量、长度、速度、角度、体积、压力、——等等。对于测量正常物体的运动速度,一般情况下比较容易求得。但是,如果是求取运动物体的瞬间速度,如抛出物体或自由落体的瞬间速度、汽车座椅受冲击时的瞬时速度等等,就比较难了。目前国内尚无此测量仪器问世。本文论述的运动物体的瞬间速度测量原理和设计制作技术,对检测物体受冲击的灵敏程度有借鉴作用。

In the scientific research and industrial production, often requires accurate measurement of various physical parameters. Such as： weight, length, speed, angle, size, pressure, etc. For the measurement of the velocity of normal objects, under normal circumstances relatively easy to achieve. However, if the strike is the instantaneous velocity of moving objects, such as free -falling objects or thrown out of the instantaneous velocity, car seat by the impact of the instantaneous speed, and so on, the more difficult. At present there is no domestic come out of this instrument. This paper describes the instantaneous velocity of moving objects measuring principle and design production technology, To examines the object the keen degree which attacks to have uses for reference the function.
