Abstract
A laser velocimetry method and system are provided. In the method, an ultrashort pulse laser is subjected to temporal broadening, beam splitting and spectrum broadening in sequence to from a three-dimensional measurement space. When an object moves in the measurement space, a first signal light s_, a second signal light s_, a third signal light s_are generated, based on which velocity components v, v, and vof the target object can be obtained, respectively, so as to obtain the velocity of the object in accordance with a formula of v=v·i+v·j+v·k.
