Abstract

Waterborne microplastics can be difficult to detect in situ. We report on a method of visualizing microplastics using their inherent birefringence. By using a full-Stokes polarization camera for measurement, the microplastics can be visualized and quantified in real-time. In addition, we show that the camera is able to visualize PET microplastics consumed by brine shrimps in vivo.
