MicroElectroMechanical System (MEMS)-Based Fiber Optic Sensor and Sensor Network for Improving Weapon Stabilization and Fire Control

摘要

A MicroElectroMechanical System (MEMS)-based fiber optic sensor and sensor and sensor network for improving weapon stabilization and fire control have bene developed. Fabrication involves overwriting two fiber Bragg gratings (FBGs) onto a polarization-preserving optical fiber core. A MEMS diaphragm is fabricated and integrated with the overlaid FBGs to enhance the performance and reliability of the sensor. A ismulation model for the MEMS fiber optic sensor network has been derived, and simulation results concerning load, angle, strain, and temperature have been obtained. The fabricated MEMS diaphragm and the overlaid FBGs have been packaged together on the basis of simulation results adn mounted on a specially designed cantilever system. The combined multifunctional MEMS fiber optic sensor and sensor network is cost-effective, fst, regged enough to operate in harsh environmental conditions, compact, and highly sensitive.
