Abstract
It is very complicated to determining the speed of object in random motion. A special instrument is described in this paper in order to detecting the object's speed in random motion. There is a column of photoelectric detecting units in the instrument. The speed and the position of the spherical object center in random motion in the vertical photoelectric detecting plane can be derived from the data gotten by inspecting of the photoelectric devices.
