Abstract
High-speed particle tracking is useful in many areas of physical and biological science. Breakthroughs in nano science such as time resolved kinesen stepping have been possible thanks to high-speed measurement of these biological processes. Traditionally such measurements are made with photo-diodes. It is possible to use these single element sensors for high bandwidth measurements but they lack the ability to track more than a single particle at a time. Another way to measure particle or multi-particles positions is with high-speed cameras. However, such cameras are limited to frame rates of 10s of kHz and often require post processing in order to extract useful information. We propose the construction of a new camera system that will be capable of measuring multiple particles at MHz frame rates while also performing inline image analysis.
