The world’s largest camera took the world’s first batch of 3.2 billion pixel photos: you can see golf balls 24 kilometers away
As part of the Rubin Observatory’s “Investigation of Time and Space Heritage” project, this camera will explore the mysteries of the universe.
A few days ago, the US Department of Energy’s SLAC National Accelerator Laboratory stated on Tuesday that researchers used the world’s largest digital camera to take the first batch of photos with a resolution of up to 3.2 billion pixels, which is also the highest resolution photo ever. .
It is reported that due to the resolution of 3.2 billion pixels, 378 4K TVs are required to display a picture completely. After the picture is enlarged, you can even see a golf ball 24 kilometers away.
SLAC National Accelerator Laboratory said, taking photo camera The imaging sensor can detect objects that are 100 million times darker than those visible to the naked eye. This sensitivity allows people to see candles thousands of miles away.
According to reports, the main reason for the ability to capture such high-pixel photos is that the camera has 189 built-in imaging sensors with a resolution of 16 million pixels. These sensors are pollinated into 25 groups, of which 21 groups are sensors. Used for imaging.
Each set of sensors is worth up to 3 million US dollars, and the installation of all imaging sensors lasted 6 months.
The camera that took these photos will be used in the Stanford University’s “Space-Time Heritage Survey” telescope at the Rubin Observatory in Chile, and will collect about 20 billion images of galaxies within 10 years to observe and study dark matter, Dark energy and other phenomena, and search for small celestial bodies that pose a potential collision threat to the earth.
In the next few months, scientists will insert a cryostat and focal plane into the camera body, and add the world’s largest optical lens, shutter and filter replacement system.
SLAC National Accelerator Laboratory said in a press release: “By mid-2021, this SUV-sized camera will be ready for final testing before starting to travel to Chile.”
