Paper Abstract
In this technique UV light is first used to mark an enduring pattern (line, grid, etc.) on a prepared fluid, and the subsequent movement of the pattern and thus the fluid is followed with visible light and high speed photography. The UV light may be pulsed (lasers, flash, mechanically chopped) or continuous, and the visible viewing light may also be pulsed or continuous (lasers, flash, sodium street lamps) depending on the requirements. Time resolution in forming the trace or in observing the trace can be of the order of 10 8 sec. and spacial resolution is in principle optical limits for light of .5μ. The experimental conditions and equipment that have been used will be discussed and compared.
