Advanced Light Source for Speckle-Free Multi-Exposure Imaging at Multi-MHz Frame Rates

Abstract

State-of-the-art high-speed cameras reach up to 10 MHz frame rates sustained over hundreds of frames long videos at a full sensor resolution. The capability allows for the capture of fast phenomena using traditional planar imaging. Combining such cameras with microscopy setups changes the range of observable movement speeds clearly distinguishable due to the magnification employed. Capturing very fast events in liquid environments, such as cavitation bubble collapse and jetting [1], or shock wave propagation above the speed of sound [2], has proven challenging.
