Abstract
In this paper, we propose, to the best of our knowledge, a novel method of simultaneously detecting and evaluating the location and size of particles from a compression particle interferogram. The 2D position of the particle can be determined with high accuracy, as evaluated by the unidirectional gradient-match with the conjoint to centroid method. The fast-Rife method provides sub-pixel accuracy and high speed for estimating the fringe frequency from the Fourier spectrum of a particle interferogram. The capability mentioned above is well verified using synthetic and experimental data. The computational load falls almost 50%, and the relative error of the measured particle diameter is less than 1.12% for homogeneous solutions of polystyrene spheres of 50 µm and 70 µm. The results demonstrate that the method presented here is considerably promising for its application to a high-density particle field, such as spray, in accurately measuring both the particle size and its location.
