Light pinpoints stress and strain – A Brillouin’t idea from OZ Optics
Remote Pipeline, Perimeter, and Structural Monitoring…
Foresight™, from OZ Optics, is a sophisticated Distributed Strain and Temperature Sensor (DSTS) based on Brillouin scattering in an optical fibre. It can measure subtle changes in both temperature and strain along the length of the fibre over time, or the rapid location detection of a major disturbance within a second.
By wrapping or embedding a fibre inside a structure, such as an oil pipeline or dam, detection of the structure being strained or heated/cooled is possible, allowing for pre-emptive maintenance. Such monitoring capability is invaluable in critical structures where cracks and failure could involve loss of life or other unprecedented costs.
Foresight™ can also detect and report larger signals within one second with only a slight loss of accuracy. This sort of response speed is ideal for security applications or strains caused by earthquakes where an immediate measurement and reaction may be required.

New Model 372 AC Resistance Bridge/Temperature Controller
Lake Shore is now offering their new Model 372 AC Resistance Bridge/Temperature Controller for experiments requiring precise and accurate AC resistance measurements.
The Model 372 has a number of improvements in design and performance for greater accuracy when making temperature measurements at very low temperatures. The streamlined front-panel keypad interface and a customisable front display along with control, configuration, and monitoring software, make the Model 372 easy to use no matter what the application.
Monitor and frequency reference outputs for direct connection to external devices or equipment are supplemented with Ethernet, USB, and IEEE-488.2 connectivity. (LabVIEW™ drivers are available)
To complement the new controller, Lake Shore have also introduced the Model 3726 scanner option designed for connecting up to 16 ultra-low temperature measurement points. With lower input noise and DC bias current, the new scanner takes full advantage of the performance improvements built into the Model 372 and offers superior performance to previous generations.

The “World’s Most Accurate” Capacitance Bridges are from Andeen-Hagerling
Andeen-Hagerling manufacture the world’s most accurate capacitance bridges and standards, and their AH 2700 models offer unparalleled stability, resolution, linearity and accuracy in a multi-frequency capacitance/loss bridges.
The numerous state-of-the-art features of the AH2700 make it an exceptionally user-friendly instrument, with unmatched precision that enables it to open up new applications in calibration, manufacturing and scientific research.
The AH2700 is the culmination of over 40 years of Andeen-Hagerling experience in bridge design and manufacture. The unique ratio transformer and the temperature-controlled, fused-silica capacitance standard make the instrument a true bridge for measuring highly accurate capacitance/loss figures which are independent of the exact test frequency (50 Hz – 20 kHz) and immune to mechanical shock.
