Time-resolved angled Fluorescence Laminar Optical Tomography (aFLOT) imaging system with 5 ms temporal resolution was developed to record 3D neural activities evoked by single whisker deflection in sensory and motor cortices of mice in vivo.
Before mass production, designed IC will be firstly verified using a Multi Project Wafer (MPW) procedure. How to package the MPW chips in a short time with a reasonable price is the common need of design houses. The Quad Flat Package (QFP) cavity carrier provides a “house” to protect the chips, and is strongly accepted by IC design companies and research parties. But usually, the QFP cavity carrier...
Over the past years, automatic traffic accident detection (ATAD) based on video has become one of the most promising applications in intelligent transportation and is playing a more and more important role in ensuring travel safety. This paper proposes a classifier-based supervised method by viewing the last seconds before motor vehicle collisions as the detection target. In our method, we devise...
We applied time-resolved angled Fluorescence Laminar Optical Tomography (aFLOT) imaging system to record 3D neural activities evoked in the whisker-barrel system of mice in vivo, in response to single whisker deflection.
In this talk I will present an array of fluorescence molecular imaging technologies for multi-scale imaging from microscopic to macroscopic scales. Specific methods include planar fluorescence imaging for macroscopic samples, fluorescence laminar optical tomography (LOT) for mesoscopic (millimeter scale) samples, and two-photon fluorescence microscopy for intravital microscopic imaging. In addition,...
We combined voltage-sensitive dye imaging (VSDi) with gradient-index (GRIN) rod lens to study neural functions in mice vibrissae system. Neural activities evoked in the thalamic barreloids by single whisker stimulation were visualized in vivo.
By applying chemical functionalization to a nanobeam photonic crystal cavity, an ultrasensitive gas-phase chemical sensor was demonstrated. Its nonlinear thermo-optical bi-stability is utilized to realize a novel threshold detector for cumulative chemical exposure.
Epidural anesthesia is one of the most widely used anesthesia methods. We developed a small hand-held OCT forward-imaging needle device for real-time epidural anesthesia surgery guidance and demonstrated its feasibility through ex vivo experiments.
We demonstrated the feasibility of OCT to image human kidneys during transplantation. OCT visualized the extent of tubular necrosis and Doppler OCT (DOCT) revealed renal blood flow dynamics that is correlated with post-transplant renal function.
Here we report the trapping behavior of a two dimension nanoscale optical lattice, enhanced by plasmon resonance in fluid. The optical potential is created by a two dimensional square lattice of metallic nanosturcutures, illuminated by an infared laser beam to excite their plasmon resonance. We observe both single and multiple particles trapping with very low optical power required. Our experiment...
A novel multichannel cavity optomechanical system consisting of a micro-disk resonator and a nano-cantilever has been proposed and implemented, which subsequently led to the first demonstration of optically induced tunable mechanical nonlinearity.
The integration of optical and radar sensors in a common area is an important task in data fusion as well as other applications. The objective of this study is to perform the feature-based registration of ALOS PALSAR and AVNIR-2 images. The proposed method iteratively minimizes the discrepancy between the feature edges in PALSAR and AVNIR-2 images. A coarse-to-fine strategy is also adopted by applying...
We demonstrated 3D Doppler optical coherence tomography (DOCT) imaging of rat kidney microcirculation within the glomerulus in vivo. Dynamic changes in blood flow were detected under altered physiological conditions demonstrating real-time DOCT imaging.
Theoretical analysis indicated FLOT resolution can be improved by angled incidence and detection. We developed an angled FLOT system and experimentally demonstrated its capability for depth-resolved fluorescence imaging in scattering medium.
We developed a novel platform based on teleoperated robot to perform highresolution optical coherence tomography imaging under continuous MRI guidance. The feasibility of real-time multi-scale imaging is demonstrated on a tissue phantom of breast tumor.
We have developed a real-time (16 frames/second), narrowest to-date (21 gauge, 700-μm-diam) optical coherence tomography (OCT) forward-imaging needle device and demonstrated its feasibility for guiding deep brain surgery based on both structural and Doppler imaging.
We have designed, fabricated, and tested a nanoparticle-embedded phantom incorporated into a model eye for characterizing the point spread function of retinal OCT devices in three dimensions under realistic imaging conditions.
We developed a co-registered optical coherence tomography (OCT) and fluorescence molecular imaging (FMI) system for simultaneous morphological and molecular imaging. This system enables real-time imaging of fluorescence-labeled gold nanoparticles and monitoring photothermal therapy.
When patients operate a home infusion pump, they maybe make some mistakes, and it will be dangerous. To detect potentially life threatening errors, we design an assistance system based on observation by multiple cameras and robust spatio-temporal algorithm. Firstly, we record the video by multiple cameras when people use the infusion pump. Secondly, we use a robust MoSIFT algorithm, which detects...
To detect errors when subjects operate a home medical device, we observe them with multiple cameras. We then perform action recognition with a robust approach to recognize action information based on explicitly encoding motion information. This algorithm detects interest points and encodes not only their local appearance but also explicitly models local motion. Our goal is to recognize individual...
