Abstract
A monitoring device for monitoring a plurality of microactuators includes an optical fiber with a plurality of sensors, each sensor being placed close to a microactuator and having optical properties varying as a function of at least one environmental parameter, the monitoring device also including a polling device with at least one transmitter/receiver for a fiber optic network, and processing means capable of modulating the frequency of the optical signal transmitted by the transmitter to select the sensor close to a given microactuator, and of comparing the received optical signal with a template characteristic of the correct operation of the microactuator, and of generating a resultant signal, representative of the correct operation of the monitored microactuator. The invention has applications in the field of health monitoring of vehicles, notably of aircraft.
