Polarimetric sensors for damage detection of aluminum materials

A PFOS for monitoring and detecting damages in aluminum specimen has been demonstrated. It has been shown that PFOS can be used to monitor the development of cracks and predict residual load on aluminum structures. The experimental result obtained is very consistent and the sensor is immune to temperature changes and electromagnetic interference, as it does not require a reference are more accurate for damage detection. Some of the features such as low cost, durable, light weight and real-time applications of PFOS have been highlighted.
