If you’ve ever tried to get that perfect shot of a race car, athlete, wild animal, or any other fast-moving subject, you know how hard it can be
– what are the odds that you’ll hit the shutter release button at just the right instant? You could try videotaping it and grabbing a still afterward, but chances are it will be grainy and blurry. It’s a common problem, but it might have just been solved. Medical researchers have developed a digital photographic technique that allows users to simultaneously shoot high-speed (slow motion) video and high-resolution stills, via the same sensor on the same camera.
The technology, called Temporal Pixel Multiplexing (TPM) was developed by scientists at the University of Oxford. They wanted a better way of imaging the rapid changes in light intensity of fluorescent molecules, inside heart cells. The scientists built their system using off-the-shelf components of digital cameras and projectors, for a fraction of the price of the equipment currently needed for similar results.
