Hacked camera captures high-speed video

Two Oxford scientists used a regular, off-the-shelf digicam and a home cinema projector to create a high-speed image capture device that records still and moving images simultaneously.

Gil Bub and Peter Kohl, physiologists at England's University of Oxford, used a normal, off-the-shelf digicam and a home cinema projector to conceive a high-speed image capture device that records still and moving images simultaneously.

The duo came up with this idea when they encountered problems aligning their high-speed videos and still pictures, taken with independent cameras, of a rat's heart muscle cells. They disassembled the projector and removed the micro mirror component, fixing it between the lens and imaging sensor of a typical camera.

The result: A budget high-speed 400fps camera that Bub said can deliver higher-resolution shots compared with what the industry offers now. By using various mirror components, the duo claimed they can record up to 6,000fps. They detail their findings in the current issue of the journal Nature Methods. Check out the video below to see how it works.
