Abstract
A novel method for measuring size of small objects with high-aspect ratio from in-line holograms by using Wigner-Ville distribution (WVD) is proposed. The proposed method provides direct calculation of the particle size by using local spatial-frequency information at the half length of holograms being analyzed. Feasibility of this method is experimentally verified by analyzing in-line holograms of an optical fiber.
