This paper presents a comparative analysis and system-level optimization of the main sensitivity enhancement methods, including mechanical amplification, functional coatings and composite embedding, interferometric schemes, and advanced spectral signal processing. A balanced integrated approach enables improvement of equivalent strain resolution. The review covers various fiber-optic sensors, including Bragg gratings and interferometers, detailing their principles and applications. Fiber optics have a significant part to play in achieving this goal and could result in an opport nity for cost savings, which increases the competitive potential, with benefits being. This paper describes the optimal design of a miniature fiber-optic linear displacement sensor. It is characterized by its ability to measure displacements along a millimetric range with sub-micrometric resolution. The sensor consists of a triangular reflective grating and two fiber-optic probes. is DRM-free for your convenience.
