Such deformation may be single degree of freedom bending of a joint and require just one sensor, or, it may be a complex combination of bending, twisting, and axial elongation which varies with sensor length, thus requiring a distributed measurement. Photonics Research Group of Aston University in UK has some publications on vectorial bend sensor applications. Relying on over a decade of experience in the fields of fiber optics, gratings and measurement devices, FBGS combines both technology and application know-how to achieve complete sensing solutions. Depending on the curvature orientation of the MCF, some of the DTGs on the outer cores will experience a relative tension or compression with respect to the central core and therefore, will register positive- or negative-induced strain changes, respectively. Instrument navigation during bronchoscopy, Energy Here are a few examples, where fiber optic shape sensing can be integrated: Biomedical Selected products Save. Technologies which rely on intensity measurements, illuminating coatings, and coarse FBG sensors are not able to resolve these distributions with sufficient granularity to accurately reconstruct complex and tortuous paths. With the TSSC technology the length of each FBG,l, is a few tens of microns andd, the distance between each FBG is zero microns, yielding a truly continuous measurement configuration.
