摘要
A fiber optic pressure transducer having enhanced resolution and dynamic range includes a fiber optic core having one or more gratings written onto it, a birefringence structure for enhancing the birefringence of the core, and a structure for converting isotropic pressure forces to anisotropic forces on the fiber core. Several different embodiments of prestressing structure are disclosed (both extrinsic and intrinsic). Several different embodiments of structure (both extrinsic and intrinsic) for converting isotropic pressure to anisotropic pressure are also disclosed. The fiber optic pressure transducer according to the invention is advantageously used in conjunction with a light source and a spectral demodulation system in order to detect pressure ambient to the fiber optic pressure transducer based on the wavelength and shift of spectral peaks.
