Abstract [en]

The aim of this experiment is to measure the particle diffusion coefficient by digital holographic imaging. We first built a digital holographic microscopy (DHM) system using a laser, an objective, and a camera. Holograms of polystyrene particles with a diameter of one micron were obtained with the system. We track the particle and use reconstruction algorithm to get 3-dimensional information in X, Y, Z direction, where X-Y plane is the plane of sample table, Z is the light propagation direction. We used the particle trajectory to estimate the particle diffusion coefficient in water. The result shows the diffusion coefficient is 4.405*10-13m2s-1, 4,479*10-13m2s-1, 3.321*10-13m2s-1 for X, Y, Z direction respectively.
