Researchers from the Singapore University of Technology and Design (SUTD) and Southern University of Science and Technology (SUSTech) in China have proposed a fabrication technique that integrates oscillation-assisted digital light processing (DLP) 3D printing with grayscale UV exposure to render an ultrafast and flexible fabrication of microlens arrays with optical surface smoothness. Optically smooth microlens array is fabricated by an oscillation-assisted 3D-printing method. Owing to the mechanical oscillation applied on the projection lens, jagged surface induced by the gaps between...Read full articleRelated content from Photonics MediaARTICLESDisplay Resolution Increases by 3D-Printing Quantum Dot NanopixelsA display technology developed at the Korea Electrotechnology Research Institute (KERI) produces 3D pixels with nanoscale dimensions by 3D-printing quantum dots (QDs) embedded in polymer nanowires....Photonics.com 8/19/20203D Printing Provides Building Blocks of HealingA group of researchers has demonstrated that assembling a network of tiny, approximately 1.5-mm3 blocks with the aid of optical technology can be an effective way to accelerate healing in tissue and...Photonics.com 8/4/2020All-Optical Ultrafast High Spatial Resolution Camera Reaches 15 Trillion Frames per SecondAn all-optical ultrafast imaging system developed by scientists at Shenzhen University has reached 15 trillion frames per second.
