Abstract
      Light of velocity is a very important physical constant, it has close relationship with dynamics, electromagnetics, optics and many theorems in recent physics, so the measurement of velocity of light has long been attached by many people。 This article has elaborated the development of the measurement of velocity of light; it respectively elaborates the measurement of velocity of light conducted by Galileo, Rosin and Michelson and put forward the importance of measurement in the history of physics。 Also, the article summarizes the development of aether theory; explore the theory of mechanism aether, luminiferous ether, electromagnetic ether, as well as whether or not the aether is existed, and the decisive significance of the aether theory towards the measurement of velocity of light。 This article elaborates the latest development of the measurement of velocity of light----the result of the laser experiment and the result of velocity of light by ways of Phase-based method which was done in our school laboratory ,then use the result and other results while measuring the velocity in order to make a comparison      and analysis。besides,we make an outlook towards the prospect of the measurment of light velocity。
                                                 
Keywords：mensuration ofvelocity of light aether theory；  aether theory；
Michelson mensuration ofvelocity of light ；   the result ofthe laser experiment
