Measurements of free-surface profile in transient flow with a simple light-slicing method

A simple light-slicing technique for the direct measurement of the free-surface shape h(x) in onedirectional transient liquid flows is studied. The method is used to determine h(x) with a precision of the order of 10−2 mm along a line several centimeters long, allowing for height differences of some...

It is useful for transient flows in rectangular channels in which capillarity and liquid adhesion at walls perturb lateral observations; the method can also be used for nondiffusive fluids in cases in which it is not advisable to add diffusive particles. © 1994 Optical Society of America.
