This is the world’s largest digital camera


The Legacy Survey of Space and Time (LSST) camera is being built by researchers at Stanford University’s SLAC National Accelerator Laboratory with the goal of capturing the night sky in unprecedented detail.Although the camera isn’t fully complete yet, all of its mechanical components are now together for the first time in one photogenic structure. 

Standing at 1.65-meter tall, LSST Camera is the largest digital camera ever constructed. The camera will be installed at the Vera C. Rubin Observatory at the summit of Cerro Pachón in Chile by the end of 2024.The 3200-megapixel camera – powerful enough to spot a golf ball from 15 miles away – is around the size of a small SUV, while its lens alone has a diameter of over five feet. Once finished, it will take digital images of the entire visible southern sky every few nights from the Rubin Observatory.Its 189 sensors take in light emanating from stars and other objects and convert it to electrical signals that can be turned into digital images. The size of each sensor is around 16 millimeters, and each packs more pixels than a single iPhone 13. The camera has 3.2 gigapixels in total and will capture images with high enough resolution to see a particle of dust on the moon. With a diameter of 1.57 meters, its largest lens is the largest lens of its kind that has ever been made.

The digital camera includes a filter-changing mechanism and shutter. It is positioned in the middle of the telescope, where the cross-sectional area is constrained by optical vignetting (edge darkening), and heat dissipation must be controlled to limit lens-deforming thermal gradients in the incoming light. The LSST camera will produce data of extremely high quality with minimum downtime and maintenance.

The team at SLAC is testing the camera shutter and the filter exchange system, two dynamic components that were also recently installed. The LSST camera will undergo one final modification – the installation of an updated refrigeration system – before the end of the year. At that point, the camera will be complete and ready for final testing before it ships to Chile in May of 2023.

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Bing Apps for Windows 8 get major updates

Late least year, Microsoft rolled out a half dozen Bing Apps for Windows 8 users, each one focused on a specific category, such as travel and sports. The apps were designed to offer “immersive vertical experiences,” and now, about six months later, a big line of updates for them is being pushed out. Users can grab the updates now by heading into the Windows Store and selecting the updates notification.
Flexible displays are the Future of IT Industry! A part from 4k and smart home appliances, the CES 2013 saw a lot of attention being drawn towards bendable, flexible displays. The elasticised display idea isn’t something new as we have seen hoards of device concepts being crafted around flexible, bendable and even foldable displays. These concept devices give us a futuristic feel, be it a flexible phone to be worn around the wrist or a phone that opens up to turn into a tablet or PSP-like device. But how far is this future? Nokia has been toying with the idea ever since we remember. The technology sounds very fascinating and the possibilities and the extent to which bendable displays could be used are vast and leave us spellbound. However, these have always been concepts and we haven’t seen any device materialise in the real world. There have been several technologies that were conceived in these years and all have been put to their practical use. But the bendable d
