Here we present an ultrahigh-speed Fourier-domain optical coherence tomography (OCT) that records the OCT spectrum in streak mode with a high-speed area scan camera, which allows higher OCT imaging speed than can be achieved with a line-scan camera. Unlike parallel OCT techniques that also use area scan cameras, the conventional single-mode fiber-based point-scanning mechanism is retained to pr...

Blinking is vital to maintain the integrity of the ocular surface and its characteristics such as blink duration and speed can vary significantly, depending on the health of the eyes. The blink is so rapid that special techniques are required to characterise it. In this study, a highspeed camera was used to record and characterise voluntary blinking. The blinking motion of 25 healthy volunteers...

Introduction: Speed cameras have been implemented to improve road safety over recent decades in the UK. Although impacts of speed camera estimated thoroughly, criteria for selecting sites rarely studied. This paper evaluates current selection UK based on performance. Method: A total 332 and 2,513 control with traffic accident data are observed from 2002 2010. Propensity score matching method em...

OF THE THESIS Content Adaptive Encoding Method for High Frame Rate Screen-Camera Communication by Yaqin Tang Thesis Director: Professor Marco Gruteser As both screen displaying speed and camera capturing speed has been improved significantly over recent years, there has been increasing interest in using this technique to explore new ways of visual communication yet remain unobtrusive to human e...

High-speed photography is an important tool for studying rapid physical phenomena. However, low-frame-rate CCD (charge coupled device) or CMOS (complementary metal oxide semiconductor) camera cannot effectively capture the rapid phenomena with high-speed and high-resolution. In this paper, we incorporate the hardware restrictions of existing image sensors, design the sampling functions, and imp...
