A number of important imaging applications, including neurobiology and precision motion analysis, require a digital camera that provides both high performance (low noise, extended linear gray scale) and high frame rates. In recent years, manufacturers have responded to this need with faster digitization/readout electronics - as high as several MHz (Mpixels/second). When combined with on-chip binning, this has enabled frame rates up to 30 frames/second from some high performance cameras. Unfortunately, even this is not fast enough for situations where two images must be acquired virtually simultaneously, or where a rapid dynamic event needs to be captured with a fast burst of images.
