Fiber Optic Sensors for Structural Health Monitoring of Air Platforms
Aircraft operators are faced with increasing requirements to extend the service life of air platforms beyond their designed life cycles, resulting in heavy maintenance and inspection burdens as well as economic pressure. Structural health monitoring (SHM) based on advanced sensor technology is potentially a cost-effective approach to meet operational requirements, and to reduce maintenance cost...
متن کاملFiber-Optic Chemical Sensors and Fiber-Optic Bio-Sensors
This review summarizes principles and current stage of development of fiber-optic chemical sensors (FOCS) and biosensors (FOBS). Fiber optic sensor (FOS) systems use the ability of optical fibers (OF) to guide the light in the spectral range from ultraviolet (UV) (180 nm) up to middle infrared (IR) (10 μm) and modulation of guided light by the parameters of the surrounding environment of the OF...
متن کاملCOMPARISON OF DIFFERENT GLASS COMPOUNDS FOR INTRINSIC FIBER OPTIC TEMPERATURE SENSORS
Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. In another study the effect of wavelength on the phase variatio...
متن کاملApplications of Structural Health Monitoring Using Fiber Optic Sensors
Fiber optic sensors have many advantages such as ease of embedding, flexible sensor size, wide temperature range, high sensitivity and etc[1]. Thus, fiber optic sensors have been introduced into many composite structures. Especially, FBG (Fiber Bragg Grating) strain sensors have noticeable attractions due to multiplexing capability, linear response and absolute measurement [2]. However, the use...
متن کاملFiber Optic Sensors
Fiber optic sensor technology offers the possibility of sensing different parameters like strain, temperature, pressure in harsh environment and remote locations. these kinds of sensors modulates some features of the light wave in an optical fiber such an intensity and phase or use optical fiber as a medium for transmitting the measurement information. The advantages of fiber optic sensors in c...
