Abstract: Provided are a particle image velocimetry and a method of controlling the particle image velocimetry. The particle image velocimetry includes a light source unit including two or more light sources that generate lights of different colors, wherein each of the light sources irradiates tracking particles in a flow field with a predetermined time difference; a camera that captures an image of the tracking particles; a controller that calculates migration distances of the tracking particles by splitting an image of the tracking particles captured by using the camera, into an image of each color, and calculates a velocity of the flow field by using the time difference at which the light of each of the light sources is irradiated and the migration distances of the tracking particles; and a display unit that receives velocity information of the flow field from the controller to display the velocity information.
