Pushing the resolution of photolithography down to 15nm by surface plasmon interference.
TL;DR: It is demonstrated numerically that one-dimensional and two-dimensional patterns with a half-pitch resolution of 14.6 nm can be generated in a 25“�nm-thick photoresist by using the structure under 193”nm illumination.
Journal ArticleDOI
Light field head-mounted display with correct focus cue using micro structure array
TL;DR: A new type of light field display is proposed using a head-mounted display (HMD) and a micro structure array (MSA, lens array or pinhole array) that drastically reduces the huge data in real three-dimensional (3D) display.
Patent
Display apparatus and system and display method thereof
TL;DR: In this article, free-form optics and waveguide technology are used to reduce the volume and weight of the display apparatus, and an optical system can be realized with improved image quality, structure, and performance parameters.
Journal ArticleDOI
Brain MR image denoising for Rician noise using pre-smooth non-local means filter
TL;DR: Comparison of the experimental results demonstrates that using a Gaussian pre-smoothing filter and VST produce the best results for the peak signal-to-noise ratio (PSNR) and atrophy detection.
Journal ArticleDOI
