Abstract:Based on digital image processing and optical scattering theory of particles, an optical measurement system for the experiment investigation on the instantaneous concentration field of turbulence is designed by using CCD. The system has such advantages as non-contact, full-field measurements, wide measurement regions and low cost. The experimental results are gotten and compared with the results given in references, which shows that the method is feasible and effective.
Keywords:concentration field  optical measurement  scattering  CCD
