Optical Difraction Tomography in Particle Image Velocimetry

Objective

Holographic Particle Image Velocimetry (HPIV) has been used successfully to make three-dimensional (3D), three-component (3C) flow measurements from holographic recordings of a seeded fluid. It is clear that measurements can only be made in regions that contain particles, but simply adding more seeding results in poor quality images due to the effects of multiple scattering. Optical Diffraction Tomography (ODT) techniques have been successfully applied to overcome the problems of multiple scattering in 2D HPIV numerical experiments by the applicant in the previous Marie Curie Intra European fellowship. The aim of this proposal is to implement these techniques for the measurement of 3D-3C velocity fields for the flow inside a few millimeter length aneurism model. The results will be compared with HPIV and Digital Holographic Image Plane interferometric measurements.
