Controller offers sufficient and stable optic power.Through the use of optic-electric circuits,with build-in intelligent algorithm design, can effectively differentiate the human signal from global noise, playing the pivotal role in the system.

it is responsible for the connections between sensing and leading fibers.  Inside the box are the fiber optic components for beam splitting and converging.

Inside the terminal junction box is optical reflective mirror, which reflects the signal back to the controller.

It can indirectly or directly sense the signals caused by the direct or indirect vibration and pressure, which producing the increase or decrease of face domain and thus providing a source for the controller to analyze.
