Optical Diagnostics Group

Research Project

Using photons to measure a wide variety of engineering parameters.


PLENOPTIC IMAGING
Plenoptic imaging involves using a camera equipped with a microlens array to capture the angular components of the light field entering the camera. The current goal is to be able to locate objects in 3D space for tracking.

PLENOPTIC PTV
Plenoptic imaging allows the 3D particle locations to be determined. Currnet work is developing a time-resolved tracking algorithm to enable single-camera 3D tracking of a fluid.

SHADOWGRAPH IMAGING OF MIRCO-CHANNEL SLOTS
Determining the rheology of the fluid based on the velocity profile from PIV measurements for flow through long mini channel.

LARGE SCALE STRUCTURES IN FLOWS
Transport and mixing can be dramatically affected by the presence of large scale flow structures. This work investigates these flow phenomenon, ways to enhance or remove and methods to control the structures.

MICRO FLUIDICS
This work develops novel measurement systems for investigating fluid mixing and transport in micro-channels. Custom epi-illumination camera systems are constructed to investigate particular phenomenon. Design and development as well as research into micro-fluidic phenomenon is conducted in this area.

OPTICAL DIAGNOSTICS
Several optical diagnostic systems are in use and under development within the group. These are mostly image based and are used for measuring velocity (PIV), concentration (PLIF) and temperature (tempPLIF) as examples.
