Lehong Wang, a professor of medical and electrical engineering at the California Institute of Technology, has developed a new camera that can capture 1 trillion frames per second of transparent objects.

This new camera, coming after Wang developed a year ago, is the world’s fastest camera that can capture 10 trillion photos per second, and its super-fast speed can take pictures of light transmission in slow motion.

But sometimes speed alone is not enough, and in fact even the fastest cameras cannot take pictures of things that cannot be distinguished or seen, so Wang developed his work and invented the new camera, according to the British Phys.Org website, Monday, January 20, 2020.

Camera technology, called Wang’s “ultra-fast and sensitive compact imaging (pCUP)”, can shoot videos not only of transparent objects, but of transient phenomena as well, such as shock waves or even signals traveling through nerves.

According to what was reported by “Arab Post”, the new imaging system combines the high-speed imaging system that Wang previously developed, with another old technology known as “contrast color optical microscopy”, which was designed to allow better imaging of objects dominated by transparency, such as The cells that make up a large part of their formation.

The heterogeneous optical microscopy technology, invented by the Dutch physicist Fritz Zernek 100 years ago, works by taking advantage of the slowing and acceleration of light waves when penetrating various materials.

For example, if a ray of light passes through a piece of glass, it will slow down as it enters the glass and then accelerate again as it exits, those changes in velocity modifying the timing of the waves.

How does the camera work?

The part responsible for rapid imaging in this system consists of a technique called Wang “LLE-CUP high-speed full encoding technology”, and unlike most high-speed video imaging technologies that capture a set of consecutive images during repeating events, the system “technology” Encoding »One shot, records all movements that occur during the capture time of that shot until its completion.

In a new research paper, Wang and his colleagues demonstrate the capabilities of the “ultra-fast and sensitive compact imaging (pCUP)” technique by depicting the propagation of collision waves through water and the transmission of laser pulses through a piece of the crystal.

Although the experiment is still in the early stages of development, it can be used in many fields, such as physics, biology, and chemistry.

“When the signals travel through the nerves, there is a very subtle expansion of the nerve fibers that we hope we can see,” says Wang. If we have a network of nerves, we can probably see their communication together in real time. In addition, it is known that temperature changes also change the optical variation, so the system may be able to visualize what is happening at the thermal separator in the combustion chamber inside the engines.
