Shape sensing with 3DSensor: laboratory beginnings
Nerve-Sensors family introduced to the market the world’s first DFOS-based displacement 3DSensor. In contrast to axial strain measurements, it allows for analysis of the shape changes (expressed directly in [mm]) perpendicular to the sensor’s axis. This patented solution has already been validated in numerous in-situ projects. However, the concept’s foundations were rigorously tested through hundreds of laboratory measurements, monitored against independent reference techniques.

Benefits of using the DFOS monitoring system
Results of using the DFOS monitoring system
Early laboratory research demonstrated the high accuracy of the 3DSensor. By adjusting its shape, strain measurements were captured through embedded DFOS fibers, allowing displacements (shape changes) to be calculated using custom algorithms. The values obtained were then compared with reference measurements at selected checkpoints, as illustrated in the plot on the right.
