Researchers at Stanford have taken 3,200-megapixel photos, the largest of all time, using sensors that will be part of the world's largest digital camera.
With this approach you can see how far digital imaging has come. The camera will be installed in Chile's Legacy Survey of Space and Time (LSST) telescope, which will study dark energy, dark matter and create “the greatest astronomical film of all time.”
The photos are so large, in fact, that it would take 378 high-definition 4K TV screens for comparison to display one of them in full size. You can also see small objects that other cameras cannot capture.
The resolution is so high that you could see a golf ball from 15 miles away, and the sensors can see objects 100 million times more blurry than visible to the naked eye. free.
This amazing performance is made possible by 189 sensors, known as charge-coupled (CCD) devices, which measure every 16 megapixels. CCDs are packaged in units called “rafts”, which make up the focal plane of the camera.
There are 21 such corks, plus four specialized ones that are not used for imaging. Overall, the focal plane contains 3.2 billion pixels. Each of them, worth up to $ 3 million per piece, was introduced into a network for the six-month focal plan.
The 3,200 megapixel images are the result of sensors that have passed an important first test. While some of the larger stake phases of the project are behind them, the team still has some difficult work to do in building the rest of the room. Final testing is expected to begin in mid – 2021.
