This short note summarizes the activity about the development and optimization of a fiber optic sensor for ultrasonic acoustic sensing to the aim of rockfall detection. The sensor is described and its viability to rockfall is discussed and experimentally validated. An improved design of the sensor, with double responsivity, is also proposed.
