Distributed Fiber Optic Acoustic Sensing Technology
Distributed Acoustic Sensing (DAS) systems detect strain changes and vibrations along optical fibers. This highly sensitive technology is used for monitoring critical infrastructure such as power cables, pipelines, or railroad tracks. DAS illuminates an optical fiber with laser pulses and measures the backscattered wave due to small random variations in the. It has many unique advantages, including, large coverage, high time-and-space resolution, convenient implementation, strong environment.
