4DSP brings fiber optic sensing technology to an unprecedented level of performance with the RTS125

June 27, 2014 — AUSTIN, TX – The RTS125 is an off-the-shelf, distributed Fiber Optic Sensing solution. With tens of thousands of strain or temperature sensors simultaneously monitored up to 100 times per second, the RTS125 offers the same sensing capabilities on up to eight channels as its predecessor the RTS150 but in a lighter and ruggedized enclosure. This product delivers reliable measurements in the most demanding environments faced by the aerospace, automotive, civil engineering, and energy sectors among others.

“The groundbreaking distributed sensing capability of the RTS125 is comprehensive because it is possible to measure many different parameters using a single system. This simplifies the collection and monitoring of diverse measurements,” said 4DSP application engineer Alex Tongue. The Fiber Bragg Gratings (FBG) enable the extraction of environmental parameters such as strain loads and temperature gradients continuously along the entire length of the sensor.

With virtually weightless sensor arrays, the RTS125 is applicable to structures of any nature where real-time changes must be monitored with precision. This instrument can be embedded as part of critical applications that require real-time monitoring. For example, it can perform structural monitoring of an aircraft fuselage during flight. The RTS125 can also be used to sense and display the three-dimensional shape of a sensor with a resolution down to 450 micrometers, enabling monitoring of pipelines or mining boreholes in oil & gas applications as well as human arteries in medical applications to accurately determine the shape of complex paths.

“As 4DSP continues to refine our line of fiber optic sensing instruments, the potential for new applications expands,” said 4DSP CTO Pierrick Vulliez. “The RTS125 is a step forward for this revolutionary technology, and its compact size, robust enclosure and increased efficiency make it an appealing choice for demanding installations with stringent limitations on physical space and power consumption.”

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
