چکیده
Wide-scale adoption of optoacoustic imaging in biology and medicine critically depends on availability affordable scanners combining ease operation with optimal performance. Here we introduce LightSpeed: a low-cost real-time volumetric handheld imager based new compact software-defined ultrasound digital acquisition platform pulsed laser diode. It supports the simultaneous signal from up to 192 channels provides hig-bandwidth direct optical link (2x 100G Ethernet) host-PC for ultra-high frame rate image acquisitions. We demonstrate use system ultrafast (500Hz) 3D human angiography rapidly moving probe. LightSpeed attained quality comparable conventional systems employing bulky electronics Q-switched laser. Our results thus pave way towards generation compact, high-performance scanners.

Design of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks
This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
متن کاملCompact lensless phase imager.
Lensless quantitative phase imaging is of high interest for obtaining a large field of view (FOV), typically the size of the camera chip, to observe biological cell material with high contrast. It has the potential to be widely spread due to its inherent simplicity. However, the tradeoff is the added complexity due to the illumination. Current illumination systems are several centimeters away f...

Introduction: Recent years have witnessed intensive interest in and the rapid development of implementations of basic operations with optics thanks to the high potential to increase signal processing speed that is several orders of magnitude higher than that of digital electronics [1]. CMOS-compatible silicon based all-optical signal processing devices could be important basic building blocks, ...
متن کاملHigh-speed All- Optical Time Division Multiplexed Node
In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...
متن کاملA High-Speed Clockless Serial Link Transceiver
We present a high-speed, clockless, serial link transceiver for inter-chip communication in asynchronous VLSI systems. Serial link transceivers achieve high offchip data rates by using multiplexing transmitters and demultiplexing receivers that interface parallel on-chip data paths with high-speed, serial off-chip buses. While synchronous transceivers commonly use multi-phase clocks to control ...
