Design device to measure the speed of objects

Abstract

Speed measurements are very important in many applications, Speed objects measuring device measure the quicken moving objects by using two lasers transit with 60 cm distance and give the time of objects passing through the two lasers and then calculate the speed by use the equation(3), wide diffusion in very different fields is due not only to the high sensitivity and reliability of laser techniques, but also to availability expenditure optical components, high quality and low-cost laser. Laser sources have been already successfully applied.
