The National SLAC Acceleration Lab has successfully experienced the largest of the currently existing digital cameras, making several gigantic photos with a resolution of 3200 megapixels.
For such a quality, scientists have placed an array of 189 individual sensors on a half-meter focal plane, each of which can do 16 megapixel pictures. The first images were not clear enough, as they were made without a lens, which was replaced by a point opening for projection with a diameter of 150 microns.
The team has already released a special program for viewing such huge pictures, since it would take 378 screens 4K to display them in full swing. However, the camera design still requires refinement. In the near future, the shutter, the sensors, the filter replacement system and the largest optical lens with three lenses with a diameter of 1.57 m, 1.2 m and 0.72 m are integrated, 1.2 m and 0.72 m. After installing all elements, it will be the size of an SUV.
The giant digital camera will be used as a telescope in the Obra Rubin Observatory, making panoramic pictures of the sky of the Southern Hemisphere for 10 years to expand the galaxic catalog «Heritage of Space and Time». The area of the focal plane is sufficiently large to capture the sky section of 40 full moons, high resolution allows you to recognize the tennis ball at a distance of 25 km, and the sensors can detect an object 100 million times the dimension of the minimum human perception threshold.
The device assembly must be completed by mid 2021. The cost of the project is $ 168 million.
