Since the circular velocity bias system enables the 3-D measurement for multiple points from a single image, the system is suitable for the measurement of unsteady phenomena such as particle movement in water flow. In this paper practical improvement of velocity bias system using multi spot laser is introduced. Using the multi spot laser, effective calibration method is established and the accurate measurement can be realized by considering the parameter of the each laser spot. The measurement of a moving surface such as a free surface of water is introduced for one of the applications of circular velocity bias system. This measurement can be realized by utilizing the peculiarity of our system and multi spot laser. Experiments show the feasibility of our method.
