What is the frame number of the best camera at present?

According to "New Scientist" reported on the 27th, scientists used an ultra-high-speed camera that can detect a single photon at 20 billion frames per second for the first time to capture the image of laser flying in the air. Within 10 minute, the researchers recorded 2 million laser pulses generated when photons collided with air. This technology can be used to patrol the corners of the environment, display invisible objects on the screen, and can also be used in places where accurate time information needs to be measured.

Scientists hope to record photon motion more accurately, which will help to develop tools for rapid angle detection. At present, it may take an hour to get the image of the first angle detection, but the new technology will be completed in a few minutes.

According to the exhibition of the Royal Society, these technologies can be used to check environmental corners. Objects placed in hidden corners will also scatter photons, and by recording these scattered light, invisible objects on the screen can be displayed. In addition, the camera can also be used in places where accurate time information needs to be measured.
