Abstract

Detection of micro-plastics in water samples is a highly pursued goal to map the distribution and abundance of these pollutants. Here we investigate the possibility to probe micro-plastics with coherent light and to image them by digital holography microscopy. From the recorded hologram, we access the phase-contrast map of the object. We show that this map can be used as a distinctive fingerprint to identify microplastics in water.
