This page represents resources such as documents and videos about Fotas. Hence, one may visualize and understand the system entirely. Distributed Acoustic Sensors look complicated but their fundamental principles are comprehensible. The videos below and the documents at the end of the page help you observe and understand the system. Videos have their own descriptions as well. In the documents section, there are Papers about our models, a Whitepaper about the device that explains the scientific background, and a Presentation that makes a summary of our Company and our Products. You may also visit our Youtube Channel.


As revealed by the video above, the system detects contraction vehicles. For example, there are two graphics on the left of the screen. Besides Volt vs Distance, there is Time vs Distance graphs. Volt vs Distance graph shows the amplitude and severity. The distance vs Time graph shows where the incident happens. Below is a clear example while the device is at work.


The system detects a fence breaching person. Waterfall graphics show breaching severity. Since it is a person, waterfall signals are not long. Undoubtedly, the system detects little signals as well.


Fiber Optic Based Distributed Acoustic Sensing is like standard acoustic sensing. For instance, a microphone is a common example of an acoustic sensor. The fiber optic cable acts like kilometers long, thousands of microphones. This is why it is called a Distributed Acoustic Sensor (DAS). In the video above, we compare fiber optic sensors and microphones. This shows the capability of the DAS.
