Abstract
Light field imaging is becoming an increasingly useful tool for measuring fluid mechanical systems. We present advances in light field imaging for fluids along three directions. The first concerns robust reconstruction of fluid measurement volumes using synthetic aperture refocusing followed by deconvolution. Then, we discuss how a flame, which distorts the refractive index, augments the light field. The error introduced into particle image velocimetry measurements by this effect is discussed. Finally, we develop a framework for the application of light field imaging to the reconstruction of a specular gas-liquid interface.
