    Description: In this paper we describe the activities carried out for the realization of an image surveillance systems, in the thermal infrared (TIR) wavelengths range, for the continuous long-term monitoring of the shallow thermal structure of the Solfatara (Campi Flegrei) and Vesuvius volcanoes. The system implementation was pursued by both acquiring and integrating all the technological instruments necessary to operate an instrumental system constituted by: a network of remote monitoring stations; a transmission system for the image data centralization; a control unit for both the remote stations control and the acquired data processing. The analysis of two-years long series of IR images collected at the Solfatara allowed us to evaluate, in the observation period, the main thermal features of the major fumarole field located in the SE inner slope of the Solfatara crater.

    Laser-slaved piezo-controlled Fabry–Perot interferometer (2008)
    American Institute of Physics
    Details
    Publication Date: 2020-02-24
    Description: A high-resolution Fabry–Perot interferometer was inserted in a feedback loop which, by monitoring elements of the fringe pattern, keeps the position of the transmitting window fixed with respect to a given line, taking into account the instability of the radiation source which would produce a wander of the line itself and the noise affecting the tuning of the receiving interferometer. The system, in this preliminary form, is able to lock itself and maintain its position indefinitely for slow and moderately fast varying disturbances.
