Vp. Kirillov et al., OPTICAL-DETECTOR FOR MEASURING THE AMPLITUDES OF INTERNAL WAVES IN STRATIFIED LIQUIDS, Instruments and experimental techniques, 37(3), 1994, pp. 359-361
The operation and static and dynamic characteristics of a contact opti
cal detector for measuring the vertical displacement of particles in a
medium with a vertical density gradient are described. The dectector
is designed for model geophysical experiments in the laboratory. Recor
ds of the vertical displacements of particles of a linearly stratified
liquid behind a hemisphere 34 mm in diameter moving at a constant vel
ocity along the bottom of reservoir filled with this liquid are obtain
ed. The measurements agree with calculations.
