Glaucoma is currently diagnosed by glaucoma specialists using specialized imaging devices like HRT and OCT. Fundus imaging is a modality widely used in primary healthcare. An automatic glaucoma diagnosis system based on fundus image can be deployed to primary healthcare clinics and has potential for early disease diagnosis. A mass glaucoma screening program can also be facilitated using such a system...
We present a two-axis microelectromechanical systems (MEMS) lens aligner with a 260 μm × 220 μm translation range that positions a 6.35 mm lens with focal length f = 12.1 mm for alignment compensation of free-space optical interconnects (FSOIs) between computer servers separated by 50 mm spacing. Efficient ultrasonic linear piezoelectric motors (PMs) provide actuation with zero power required to hold...
A low cost, blind mate, injection molded optical backplane is presented. The optical backplane consists of a 12 channel optical broadcast bus operating at 10Gbps/channel with six blind mate optical output ports spaced 1U apart.
Buses have historically provided a flexible communications structure in computer systems. However, signal integrity constraints of high-speed electronics have made multi-drop electrical busses infeasible. Instead, we propose an optical data bus for computer interconnections. It has two sets of optical waveguides, one as a fan-out and the other as a fan-in, that are used to interconnect different modules...
Terabus is based on a chip-like optoelectronic packaging structure (Optochip) assembled directly onto an organic card with integrated waveguides (Optocard). To-date, Terabus has demonstrated 4times12-array optical transmitters and receivers operating up to 20 Gb/s and 14 Gb/s per channel
