What is fbg sensor array, and what are the differences with fbg array

"FBG sensor array" and "FBG array" emphasize slightly different aspects.FBG Sensor Array:

• Definition: FBG sensor array refers to the distribution or arrangement of multiple FBG sensors in a certain area, which can be on one or multiple Fiber Bragg Grating sensors.
• Features: This term emphasizes the multiple configuration of FBG sensors, covering the overall layout of multiple grating sensors, not just focusing on a single Fiber Bragg Grating sensor.

FBG Array:

• Definition: FBG array typically refers to the configuration of multiple FBG measurement points on one or more fibers, forming an array structure.
• Features: This term emphasizes the array nature of FBGs, encompassing multiple Fiber Bragg Grating measurement points on a single fiber or on multiple fibers.

In practical use, these two terms are often interchangeable because they both denote the arrangement of multiple FBG measurement points in an area to achieve multi-point measurement or monitoring.Therefore, the difference between them is mainly reflected in the emphasis on whether the FBGs are individually highlighted. In some contexts, "FBG array" might emphasize the overall structure and configuration of the entire array, while "FBG sensor array" might place more emphasis on the layout of individual sensors.
