We propose an original cylindrical interferometric out-of-focus imaging setup to realize the characterization of spherical droplets in a volume. The longitudinal position of the droplets is determined through the orientation of the fringes while the diameter of the droplets is obtained from the frequency of the fringes. The experiments agree with the simulations. (C) 2012 Optical Society of America
