Abstract
The article describes a comparative measurement of a classical seismic sensor and a fiber-optic interferometric sensor for the perimetric applications. We created and proposed technically and financially the simplest interferometric sensor (type two-arm Mach Zehnder). A test polygon was created where were analyzed the vibration-acoustic manifestations caused by the 20 test subjects. The article describes original results that clearly point to the high sensitivity of the interferometric sensor.
