About AFDL

In fluid dynamics, one of the main questions being asked is: How can flow field measurements be taken? Today, the even better question to ask is: How can measurements be taken three-dimensionally? While most current approaches are composed of complex systems or can be quite expensive, the emerging technology centered at the heart of AFDL is the plenoptic camera (right, top). We have the capability to construct these unique cameras within our laboratory. What separates a plenoptic camera from a conventional camera is the placement of a microlens array (right, bottom) in front of the image sensor. We currently possess 16 MP and 29 MP cameras, and we have also constructed plenoptic cameras for Sandia National Laboratories in New Mexico as well as Florida State University. 

The plenoptic camera allows three-dimensional information to be obtained from a single snapshot. The plenoptic camera records light just like a conventional camera, but instead of just recording the 2D position or projection of scene on the image sensor, it can also record the angle the light is coming into the camera. This allows our research group to process data computationally after the image is taken to refocus the image, change the image’s perspective, and explore volumetric reconstructions. 

This technological advancement is allowing the next generation of optical diagnostics to develop. AFDL is able to start exploring a variety of advanced fluid diagnostics problems. Our current research involves Volumetric Particle Image Velocimetry, Schlieren and Background Oriented Schlieren techniques, Reacting Flow Imaging, Multi-phase Flows, exploration of potential Gas Turbine Imaging, Volumetric Reconstruction, and Range Finding Algorithms.
