A method of three dimensional velocities measurement is applied to flow in micro channel. Method of using stereo camera is ordinarily used as three dimensional PIV method. However the stereo camera method has complicated processes, such as setting camera parameters, matching spatial and time correlation between two corresponding stereo images, calculating the three dimensional velocities. The dimensions of channel for the experiment are 0.17 millimeters width and 0.61 millimeters depth. Water under the room temperature flows vertically in the channel. It is supposed the velocity component perpendicular to main flow is small. In this case, parallel multi images perpendicular to ray of camera as parts of three dimensional flow are useful. Parallel images can obtain by making to change distance from camera to subject. The method in this paper is setting a thin glass between camera and subject. This method is simpler than stereo camera method.
