Visualization of Liquids Flows in Microfluidics and Plasma Channels in Nanosecond Spark Microdischarges by Means of Digital Microscopy

An application of digital optical microscopes for visualization of single-pulse or pulsed-periodic processes in microfluidics and physics of spark microdischarges is studied. Multiple examples of coagulation processes of liquid microvolumes, nanosecond spark discharges near liquid drops and plant living tissues in a cell-size level are provided.
