Optical Flow Diagnostic Technique Development
1) Holographic PTV for 3D Flow Measurements: From Microfluidics to Wall-bounded Turbulence
3D Velocity, Shape and Concentration Measurements
Microfluidics: <70 um vector spacing for 2 mmx 2 mm x 1 mm (sreamwise x spanwise x wall-normall)
Turbulent Channel Flows: < 1.1 mm vector spacing for 20 mmx 20 mm x 50 mm (sreamwise x spanwise x wall-normall)
Recognition and classification of red blood cells
Study Motile Marine Organisms, < 13 um wall proximity for velocimetry
