Revolutionizing Railway Safety with Distributed Acoustic Sensing (DAS)
Stretching thousands of miles beneath your feet, a web of fiber optic cables listens to vibrations. Activities above ground, such as walking or driving, create characteristic vibrations that slightly disturb the way light travels through these cables. With the right equipment, scientists can interpret these disturbances to identify their sources and timings, to increase safety. What is DAS? This technique, known as distributed acoustic sensing… Read More »Revolutionizing Railway Safety with Distributed Acoustic Sensing (DAS)
