A team of researchers has developed a device that allows you to capture images of what is happening inside living cells in real time.
Previously, it could take half an hour for one such picture in the laboratory, but processes such as DNA coding and protein assembly are instantaneous. Scientists from the Chinese Academy of Sciences in Shanghai have found a solution to this problem by combining two technologies in one detector..
The created camera registers photons and light particles coming directly from the target and reflected from it. This imaging method allows you to get a complete image of the object, even if the light detector can only pick up a small amount of radiation..
However, since photons are waves, the resolution of such a survey is limited to 200 nanometers. To overcome this barrier, the team used ultra-high resolution microscopy technology..
In fact, they combined the two devices into one system, and increased the number of single-pixel sensors so that a clear image can be obtained in one frame. To improve the clarity of the images, scientists installed a computer-controlled phase modulator in front of the light detector to generate sharper characteristics..
In their experiments, they were able to take a photo with 80nm resolution in one frame and 60nm resolution in 10 frames, finding that each shot takes only one thousandth of a second..

Not only are they becoming more perfect cameras for studying nanoobjects, but also for long-range shooting. Formerly engineers presented an active optical system capable of shooting objects at a distance of 45 km even through the smog.
