New Camera Can Take Images at Speed of Light
Scientists have improved upon a new camera technology that can image at speeds about 100 times faster than today’s commercial cameras and could enable imaging of ultra fast processes involving neurons, combustion and stars.The new technology also opens a host of new possibilities for studying extremely fast processes such as neurons firing, chemical reactions, fuel burning or chemicals exploding. ultra fast photography (CUP) camera that can image at speeds of 100 billion frames per second in a single camera exposure – fast enough to capture travelling light pulses.
It is the world’s fastest receive-only camera, meaning that it can use available light for imaging and does not need additional illumination from a laser or other light source.The new method improves the resolution and quality of images captured with CUP.
They demonstrate the CUP upgrades by capturing a movie of a pic second laser pulse travelling through the air and also by pointing laser light onto a printout of a toy car to create a movie of the light reaching different portions of the car at different times.Researchers are particularly interested in understanding how the brain’s neural networks operate.Using the new camera with a microscope could allow them to watch neurons fire by capturing extremely fast chemical processes called action potentials that travel through an axon at speeds that can reach more than 100 meters per second.
The improved image resolution and quality means that the camera could better capture entire action potential events, including the initiation of the action potentials, propagation with varying speeds, and the termination of signalling.
