Abstract
An improved fiberoptic pressure sensing system is disclosed by tapering the tip end of an optical fiber, or alternatively, by tapering or bundling a fiber or group of fibers within a connector. By selectively joining together fibers with a taper while tailoring numerical apertures of the connected fibers, a fiberoptic pressure sensing system is provided with an enhanced ability to increase sensitivity and signal-to-noise performance.
