Abstract: A technique of flow visualization employing a laser to generate a sheet of light and at least one beam of light, wherein the beam of light is caused to scan or sweep the sheet of light. Receiving optics and one or more photo detectors monitor the interaction and provide as output as a function of the velocity of particulate matter present in the area of intersection of the light beams, thereby generating a velocity picture of the scanned area which may be processed and stored or presented on a cathode ray tube or other display device.
