Applications of High Speed Video

• Rowland Institute at Harvard has performed extensive studies on swimming Escherichia coli. Their recently published "On Torque and Tumbling in Swimming Escherichia coli" used high speed, fluorescence microscopy to image the 0.012 micron diameter flagelar filaments undergoing polymorphic transformations during rotation reversal. The high rotational speed of the filament bundles and low light levels were captured using an HSC-500x2 camera. A brief movie may be viewed here.
• The Department of Neurobiology and Anatomy at Drexel University is studying the "Responses of Trigeminal Ganglion Neurons during Natural Whisking Behaviors in the Awake Rat." An HSC-250x2 camera captured high resolution images, recorded with an HSR-200S video cassette recorder allowing recording sessions to last up to 25 minutes. A GL-250 time text inserter overlaid time in milliseconds to allow correllation with Neural Recordings.
• Georgia State University's Biomechanics and Ergonomics Laboratory was the central meeting facility of the IOC Medical Commission's Subcommision on Biomechanics and Physiology of Sport. Fourteen of nineteen research projects used high speed video.
• Case Western Reserve University with Henry Ford Hospital is studying the relationship between dynamic knee instability, meniscal breakdown, and osteoarthritis. They are assesing knee dynamic instability using an unique, high-speed, biplanar radiography system.
• NASA Ames Vision Group is using high speed video cameras in their research on Eye Movement Metrics Of Human Motion Perception And Search
• The University of Colorado at Boulder, Department of Integrative Physiology is researching the biomechanics, energetics, and neural control of walking and running to understand the mechanical principles which set the limits of performance.
• The Museum of Vertebrate Zoology at University of California, Berkeley is using high speed video to study feeding behaviour of salamanders. Their salamander research website includes some video clips made by Stephen Deban.
