The whole stroy is rewrited from the story "Little Red Riding Hood". This game is an action and side-scrolling video game. They use FLASH and RPG MAKER to make RED and the post-production is PS (PhotoShop). "With their ability to flatten and shrink optical components while drastically enhancing performance, we believe that optical metasurfaces can be applied not only to image sensors but also to various optoelectronics devices such as those used in displays, projectors and augmented or virtual reality devices.RED is a game which made by three university students. "We hope our work will further boost the development of practical optical devices and systems based on metasurfaces," said Miyata. Now that they have demonstrated the new sensor concept, the researchers plan to create and test an integrated device by directly mounting a metalens array onto an image sensor.
Optical simulation studies also showed that the metalens-based sensor architecture exhibited less image degradation due to sensor noise, which is often the limiting factor in dark-scene or ultra-fast imaging. This experiment showed that, compared with a filter-based sensor, the metalens-based sensor generates color images with 2.83-fold enhanced signal levels without sacrificing color quality. The researchers used an optical microscope to mimic the way that light would travel through a metalens array before reaching a sensor. The efficiency of color sorting and focusing into each target pixel can be observed. This color microscopy image shows the measured light profile on the sensor pixels under normal illumination. "These new sensors could one day let people more easily capture night views with smartphones or enable new cameras that accurately capture high-speed objects, which will be useful in security and autonomous driving." "We envision our metalenses playing an important role in the development of filter-free color image sensors that exceed current sensitivity limits," said Miyata. And because the new metalenses are made using a CMOS-compatible process, they could easily be integrated onto current sensors to create filter-free imaging devices. In Optica, Miyata and colleagues report that filter-free color sensors made with the new metalenses significantly enhanced signal levels without sacrificing color image quality or spatial resolution. "Our new metalenses are made from a highly-engineered surface that can collect light while simultaneously separating primary colors without any color filters, opening a pathway to dramatically improve sensitivity."
"Traditional imaging sensors such as the ones used in smartphones, wearable devices and autonomous vehicles have a limited sensitivity because they rely on color filters placed over each pixel," said research team leader Masashi Miyata from NTT Device Technology Labs in Japan.
