Three-dimensional microscopic light field particle image velocimetry, 2017

Abstract: A microscopic particle image velocimetry (μPIVμPIV) technique is developed based on light field microscopy and is applied to flow through a microchannel containing a backward-facing step. The only hardware difference from a conventional μμPIV setup is the placement of a microlens array at the intermediate image plane of the microscope. The method combines this [...]
