At the Rio 2016, just one high-brightness laser projector was used on an experimental basis. This then led to the development of commercial products offering 30,000-lumen levels of brightness. Shuji Teranishi of Connected Solutions Company, Panasonic Corporation, who worked on these projectors, told us about this process.
"A key development theme for our laser projectors toward the PyeongChang 2018 Opening/Closing Ceremony was to increase the brightness further and create more powerful pictures. It goes without saying at Panasonic that we should pursue better brightness, picture quality, and color reproduction, but our team of engineers led the way toward combining this with the stability, lightness, and compactness that a laser light source can provide."
