chip based wide Field of View nanoscopy
Nature Photonics, 2017Co-Authors: Robin Diekmann, Øystein Ivar Helle, Peter Mccourt, Thomas R Huser, Mark Schüttpelz, Balpreet Singh AhluwaliaAbstract:Present optical nanoscopy techniques use a complex microscope for imaging and a simple glass slide to hold the sample. Here, we demonstrate the inverse: the use of a complex, but mass-producible optical chip, which hosts the sample and provides a waveguide for the illumination source, and a standard low-cost microscope to acquire super-resolved images via two different approaches. Waveguides composed of a material with high refractive-index contrast provide a strong evanescent Field that is used for single-molecule switching and fluorescence excitation, thus enabling chip-based single-molecule localization microscopy. Additionally, multimode interference patterns induce spatial fluorescence intensity variations that enable fluctuation-based super-resolution imaging. As chip-based nanoscopy separates the illumination and detection light paths, total-internal-reflection fluorescence excitation is possible over a large Field of View, with up to 0.5 mm × 0.5 mm being demonstrated. Using multicolour chip-based nanoscopy, we visualize fenestrations in liver sinusoidal endothelial cells. Nanoscopy on a chip makes it possible to perform super-resolution imaging of biological specimens with a wide Field-of-View.

Super-resolution modeling and visualization system with wide Field of View
2020Co-Authors: Hajime Nagahara, Yasushi Yagi, M. YachidaAbstract:Many applications in virtual reality and multimedia require to show a realistic virtual environment. High-resolution and wide Field of View are some important factors of the reality. We proposed two techniques; super-resolution modeling and wide Field of View catadioptrical head mounted display to enhance a reality for such applications. Super-resolution modeling improves a resolution of model that constructs the virtual View. The wide Field of View HMD realized 180-degree Field of View horizontally including human peripheral vision.

Wide Field of View catadioptrical head-mounted display
Proceedings 2003 IEEE RSJ International Conference on Intelligent Robots and Systems (IROS 2003) (Cat. No.03CH37453), 2003Co-Authors: H. Nagahara, Y. Yagi, M. YachidaAbstract:Many applications have used a Head-Mounted Display (HMD), such as in virtual and mixed realities, and tele-presence. The advantage of HMD systems is the ease of feeling a 3D world in the display of animation or movies. However, the Field of View (FOV) of commercial HMD systems is too narrow for feeling immersion. The horizontal FOV of many commercial HMDs is around 60 degrees, significantly narrower than that of humans. In this paper, we propose a super wide Field of View catadioptrical head-mounted display consisting of an ellipsoidal and a hyperboloidal curved mirror. The horizontal FOV of the proposed HMD is 180 degrees and includes the peripheral View of humans. It increases reality and immersion of users. As well, the central region (60 degrees) of the FOV can measure 3D distances using stereoscopics.
