Abstract

An optical-based sensing apparatus and method are provided. A sensing apparatus (10) may include a tube (30). An optical fiber (12) may be encased in the tube. A buffering layer (14) may be interposed between the optical fiber and the tube. The buffering layer and/or the tube may be selectively configured to form along a length of the apparatus a plurality of optical sensing zones (16, 18, 20) spatially arranged to sense parameters involving different parameter modalities.
