Paper Abstract

This paper presents a measurement method used to precisely measure the diameter of water jet. A He-Ne laser is coupled into the water jet as the light source, and the image of the water jet is captured by a CCD. The diameter of water jet can be thus measured from the captured images by such processing as sharpening, filtering, subpixel locating and fitting. Experimental results indicate that the proposed method can be used to make real-time measurement of the diameter of water jet with a simple and low-cost set-up. The method can also be used to measure the break-up length of water jet by introducing a microstage along the direction of water jet.
