FBGs and heart procedures
Study finds FGB sensors can help make delicate heart procedures safer.
Researchers from the Texas Heart Institute and University of Houston recently published results of their work with FBG sensors in the journal Sensors. The article, 'FBG Sensor for Contact Level Monitoring and Prediction of Perforation in Cardiac Ablation', (webpage) details why surgeons need more information about the condition and position of heart catheters during a procedure. Specifically, an ablation catheter must be pressed against the heart wall with sufficient pressure to complete the procedure, but without so much pressure that the catheter actually pokes through the wall. As you might imagine, perforating the wall is not good news for the patient.
The FBG is specially packaged within the catheter to indicate the pressure on the end. A change in the pressure results in a corresponding shift in the measured Bragg wavelength. A Micron Optics' sm130 optical sensing interrogator (as pictured) was used for these crucial measurements.

Micron Optics Weir-Jones case Study
Micron Optics have released a press release and case study on a major oil pipeline monitoring project with Weir-Jones.
Over the past decade, fiber optic sensing (FOS) has become widely accepted and adopted for structural health monitoring (SHM) of bridges, buildings, towers and other large structures. More recently, the oil and gas industries have turned to fiber optic sensing for a variety of applications, including pipeline integrity monitoring, intrusion, and leak detection.
This example saw the use of the si225 rack mount interrogator, as shown below, situated 1km away from the pipeline.

Price reduction reminder
Don't forget that Micron Optics have introduced significant savings on the price of not only temperature compensation sensors but also the dynamic interrogators. With certain sensors' prices slashed by over 60% and the dynamic interrogators by up to 50% there's never been a more affordable time to be using the highest quality in sensing equipment.
