Tham khảo tài liệu 'overview of fiber optic sensors phần 1', kỹ thuật - công nghệ, kĩ thuật viễn thông phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Overview of Fiber Optic Sensors Over the past twenty years two major product revolutions have taken place due to the growth of the optoelectronics and fiber optic communications industries. The optoelectronics industry has brought about such products as compact disc players laser printers bar code scanners and laser pointers. The fiber optic communication industry has literally revolutionized the telecommunication industry by providing higher performance more reliable telecommunication links with ever decreasing bandwidth cost. This revolution is bringing about the benefits of high volume production to component users and a true information superhighway built of glass. In parallel with these developments fiber optic sensor 1-6 technology has been a major user of technology associated with the optoelectronic and fiber optic communication industry. Many of the components associated with these industries were often developed for fiber optic sensor applications. Fiber optic sensor technology in turn has often been driven by the development and subsequent mass production of components to support these industries. As component prices have fallen and quality improvements have been made the ability of fiber optic sensors to displace traditional sensors for rotation acceleration electric and magnetic field measurement temperature pressure acoustics vibration linear and angular position strain humidity viscosity chemical measurements and a host of other sensor applications has been enhanced. In the early days of fiber optic sensor technology most commercially successful fiber optic sensors were squarely targeted at markets where existing sensor technology was marginal or in many cases nonexistent. The inherent advantages of fiber optic sensors which include their ability to be lightweight of very small size passive low power resistant to electromagnetic interference high sensitivity wide bandwidth and environmental ruggedness were heavily used to offset their major .
