Dynamic Liquid Surface Shape Measurement
Fourier transform profilometry (FTP) is used for dynamic liquid surface shape measurement. A sequence of dynamic deformed fringe images can be grabbed by CCD camera and saved on disk rapidly. By Fourier transform, filtering, inverse Fourier transform and unwrapping these phase maps in 3 D phase space, the shape of a vortex at different times is obtained. The experimental results show that FTP can efficiently deal with the dynamic liquid surface shape measurement.
