Design of a 3MPa Fiber Optic Pressure Sensor
We designed a flexible fiber optic pressure sensor for contact force detection based on the principle of backward Rayleigh scattering using a single-mode optical fiber as the sensing element and polymer PDMS as the encapsulation material. Fiber-optic sensing (FOS) technology has emerged as a cutting-edge research focus in the sensor field due to its miniaturized structure, high sensitivity, and remarkable electromagnetic interference immunity. Compared with conventional sensing technologies, FOS demonstrates superior capabilities in.

How to measure the inner hole using a fiber optic sensor
In this paper we describe a probing method, referred to as Fiber Deflection Probing (FDP), for use on Coordinate Measuring Machines (CMM). Examples include the inner surfaces of micro-drilled holes, narrow gaps or complex free-form surfaces. The optical inspection technique offers a fast, contactless and wear-free way of measuring micro-structures and distances. Measurement of diameter and form of small holes is of great importance in applications such as fuel injector nozzles, fiber optic ferrules, wire drawing dies, holes in printed circuit boards and medical apparatus such as syringes, etc.
