Photoshop filters for safer bridges (w/ Video)

How can we constantly monitor the stability of a bridge or detect a leak in a gas pipeline in real time? A method based on optical fibers has become the norm in recent years. By carefully measuring the path of light in fibers up to 100 kilometers long, we can glean information on the temperature, pressure and intensity of magnetic fields along the entire length of the fiber. It's similar to a nerve, which tells us the intensity and location of a stimulus.
