Dmitriy Yavid - Broad Shoulder Consulting
Photo detectors have become ubiquitous, amazingly good and inexpensive. Still, there is an ever-increasing demand from all corners of science and industry to expanded their range of wavelengths, for wider bandwidth, higher sensitivity and lower noise. In this overview of both single-pixel and array detectors, the quest for better devices is explored which covers approaches including material sciences, device design and optimization, miniaturization and cost reduction.
Mixed Domain Oscilloscopes: Discover the Possibilities
Alan Wolke - Tektronix
The Mixed Domain Oscilloscope is a new category of test equipment that features new levels of convenience, efficiency, cost savings and cross-domain measurement capability that had been previously unavailable in a single instrument. Two families of Mixed Domain Oscilloscopes are discussed, each bringing a unique and powerful blend of measurement and analysis across analog, digital and RF domains.
Fiber Optic Links for RF and Microwave Systems
Howard Hausman - MITEQ
An ideal interface between RF and Microwave systems is one that has minimal distortion, i.e. a flat frequency response and linear phase over the band of interest. Coaxial cables satisfy most of these requirements but have limitations that show up at higher frequencies, wide bandwidths, and long distances. Fiber optic links in contrast have lower losses and less frequency dependence over long distances, making it a desirable and sometimes necessary technology to consider when components are not located close to each other.
This technology opens various applications to a wider range of possibilities, such as interfacing with antennas, measuring systems over large geographical areas, remote communication systems, etc. all in secure non-interfering environments. The disadvantage of Fiber optic links versus coaxial cable is that the link is not a passive component and therefore has associated dynamic range issues. Presented in this discussion is an analysis of the key fiber optic components, a method of relating key parameters to typical microwave component parameters and some typical applications of microwave system using fiber optic links to enhance their performance.
Opportunities & Challenges in Managing American Technology
M. Abdul Awal - North South University,
Though the whole world is undergoing a huge paradigm shift in technological advances, United States of America is still retaining its technological superiority against other countries in areas, such as: mobile communications, social networking, nano technologies etc. But do these technology inventories of USA generate sources of new revenue in export trade or enhance its global competitiveness? Can Academia play any key role in this arena by teaming with government and industry?
This talk elaborates the key issues and suggest how the future national R&D strategy should be redesigned allowing Academia to play a pro-active role in the economic growth of America via assisting better management of engineering and technologies. It also analyzes the value chain of products and services with suggestion, how the US can retain the high value chain components via appropriate management of its technological strengths.
