High-speed camera system for biological applications in optical tweezing

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 photodiodes. 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.
