In the framework of EDISECUR project, funded by the Lazio region, a prototype of speckle tracking remote infrasonic sensor, TIS, for measuring the fundamental angular velocity, and harmonics of a surface subject to oscillations, was developed. TIS is particularly suitable for the detection and monitoring over time of buildings, bridges and other artefacts. Knowing the vibrational state of these structures can be of interest both for their dynamic characterization and for safety. This compact prototype, gives an immediate measure of angular velocity and, with simple operations, it is possible to deduce angular displacements and accelerations. From the angular quantities and the geometric dimension of the surface, it is shown how it is possible to determine other linear kinematic...
