This fiber optic sensing device is composed by an interrogator capable to communicate and process signal from high-density optical fibers for strain and temperature measurements.
The fully ruggedized RTS125+ fiber optic sensing instrument was created in partnership with NASA to support the test and validation of their new vehicles. It delivers the most reliable measurements for structural testing, design optimization, structural health monitoring, thermal mapping and 2D shape sensing. Its compact size, robust enclosure and increased efficiency make it the only viable product for environmentally demanding installations with stringent limitations on physical space and power consumption. 
At A2SRL, this equipment is used to measure the strain of aero structures in high-resolution on bench or wind tunnel tests. It is used to support modal analysis and shape reconstruction of flexible structures.
