| Abstract: | PIV(Particle Image Velocimetry)technology is one of novel measurement technology applied in fluid field.Not only the magnitude but also the direction of velocity of fluid field can be obtained through PIV.In this paper according to the discussion of the physical model of PIV and the demand of measuring high speed flow field,Adjustable Digital Pulse Synchronizer was approached and designed.Through the very technology not only was the field straddling technology realized but the better result was obtained when applied into the real flow field. |
