抄録
A new technique for the particle depth and size determination is implemented and tested by using synthetic as well as experimental hologram images. The particle depth and size are detected by geometric measures of the particle signal peak in the reconstructed images. Performance tests are carried out with different holograms patterns consisting of different sizes particles and overlapping interference fringes. The results obtained in both synthetic and in experimental holograms demonstrate the potential of the present method to the flow measurements.
