Holographic 3D Touch Sensing Display

Digital Holography & 3-D Imaging Meeting, 2015
A 3D image floating in the air is reproduced by a 3D light-field display using a holographic screen, and a 3D touch interface is implemented by detecting the touch to the reproduced real image.

Digital 3D vibration sensing module

2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2018
Vibration sensing technology is a fundamental issue in smart machine and environmental vibration monitoring, etc. In this paper, we propose a digital 3D vibration sensing module using electronic resonator, three mechanical spring-switches, embedded microprocessor unit (MCU) and the algorithm of frequency to event.

3D astigmatic depth sensing camera

SPIE Proceedings, 2011
Three-dimensional displays have become increasingly present in consumer markets. However, the ability to capture threedimensional images inexpensively and without major modifications to current cameras is uncommon. Our goal is to create a modification to a common commercial camera that allows a three dimensional reconstruction.

3D Integrated Physicochemical‐Sensing Electronic Skin

Small
Abstract The integration of physical and chemical signal sensing is of great significance to bridge the gap between electronic skin (e‐skin) and natural skin. However, the existing method of integrating physical and chemical signal sensing units in two dimensions is not conducive to the development of e‐skin in ...

Fiber-Optical 3D Shape Sensing

2014
Fiber Bragg grating (FBG) technology is well known since more than three decades. It started in 1978 with the discovery of photosensitivity in optical fibers by Ken Hill et al. [1] when illuminating germanium-doped silica fibers with visible argon ion laser radiation.

High-performance 3D Compressive Sensing MRI reconstruction

2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010
Compressive Sensing (CS) is a nascent sampling and reconstruction paradigm that describes how sparse or compressible signals can be accurately approximated using many fewer samples than traditionally believed. In magnetic resonance imaging (MRI), where scan duration is directly proportional to the number of acquired samples, CS has the potential to ...
