Abstract
Projecting an orthographical grating mask (20pl/mm) on the surface of a small liquid bridge and receiving the reflected distortion image, on e can calculate out reversely the shape of free surface of a liquid br idge. In this way we measured the surface shape of a small floating zo ne and the two-dimensional deformation of its vibration. The mechanism of thermocapillary oscillatory convection and the three-dimensional v ariation of the free surface are revealed experimentally. The principl e for space experiment has been studied in our laboratory.
