Researchers have created a new ultra-fast camera that is capable of capturing transparent objects and even such fleeting phenomena like shock waves or signals passing through neurons.

In 2018 year scientists from the California Institute of Technology have developed the fastest Today camera that takes up to 10 trillion images per second, allowing you to capture even slow motion of light. but sometimes one only speed is not enough. therefore the team presented other variant of the device that working slower but has more uses.

New imaging system based on phase-sensitive compressed ultrafast photography technology. She combines the system high-speed photography and technology phase contrast microscopy, which improves visualization. Insofar as light waves change their speed when passing through transparent materials, then using optical receptions scholars may measure these temporal differences, making them easier to see.

The system also includes the so-called compressed ultra-fast coding technology. without losses. She takes single shots, not a series, capturing all movement, which happens in the time it takes for completion of the frame, which allows capture even fleeting phenomena.

During their research, the team demonstrated the capabilities of the new camera by capturing the propagation of a shock wave in water and a laser pulse passing through a piece of crystalline material..

The developers argue that in the future with the help of such a system can will be see small expansions of nerve fibers as signals pass through them, which will allow see the interaction of a whole network of neurons in real time.
