Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable.

High-Speed Switched Serial Fabrics Improve System Design

Well into its third decade of widespread deployment, VME adopted the new VXS gigabit serial interface, clearly representing the most significant leap in backplane data transfer rates throughout its entire history. Because VXS delivered such a dramatic improvement in embedded system performance, the use of gigabit serial technology was extended to create VPX. The OpenVPX initiative followed shortly thereafter, as risk-averse government agencies mandated the need for industry-wide standards. The hallmark of any successful standard is that it continues to evolve with technology, and none offers a better example than VME’s evolution to VXS and VPX.

High-Speed Real Time Recording Systems

In today’s world of high-speed A/D converters operating in the gigahertz range, real-time signal recording has become a challenging task that requires specialized hardware and intelligent application software. When designing a real-time recorder capable of streaming sustained data to disk at rates of up to 5 GB/sec and higher, the system developer has to consider the limitations presented by the recorder’s operating and file systems, the limitations of disk drive technology, the hardware interfaces, and the RAID controller technology.

Putting FPGAs to Work in Software Radio Systems

FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.

Critical Techniques for High-Speed A/Ds In Real-Time Systems Handbook

To help define the meaning of “high-speed A/D” used in this handbook, we will be focusing primarily on A/D converters with sampling rates higher than 100 MHz. We will review sampling techniques, FPGA technology and we will present the latest Pentek high-speed A/D products and applications based on them.

Software-Defined Radio Handbook

SDR (Software-Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing.This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace legacy analog receiver and transmitter designs while offering significant benefits in performance, density and cost.
