Paper Abstract

To visualize the 3D motion history of a particle, an analysis method has been developed for streak holography. The method is based on the fact that inline hologram of a particle has circular fringe pattern that can be calculated either Mie scattering theory, or Fraunhofer or Fresnel diffraction theory. Generalized formulation of the analysis method has been made under the assumption of circular fringe patterns followed by giving various fomulae for the case of Fraunhofer approximation. The image analysis can be further simplified at discrete times when one of the fringes is just tangent to the camera slit. This method is successfully applied to one of particle streak hologram to obtain 3D trajectory of it. The results of these examinations suggest the feasibility of streak holography for the visualization of particle field such as aerosol transport, combustion, multiphase flow, etc.
