Abstract 3D measurements of burning coal particles in the flame are challenging and of
great interest. Digital inline holography is applied to perform 3D measurement of coal …

The burning behaviors of an individual coal particle in the combustion of a cloud of coal
particles is of great importance because it represents the realistic situation of pulverized coal …

Digital holography is applied to the reconstruction of small particles in a plane whose
orientation is arbitrary as specified by the user. The diffraction pattern produced by the …

We present the preliminary results of a digital holographic system that can determine the two-
dimensional velocity vector fields in several slices of a sample volume. A CCD camera …

Wavelet ridge techniques utilizing daughter wavelets under two different kinds of definitions
in the optical fringe pattern analysis are theoretically clarified. The clarification reveals that …

Digital in-line holography is applied to studying the trajectories of individual water droplets in
airflow. In order to track the particles, multiple exposure holography is performed using a …
