A REVIEW ON TYPES AND APPLICATION OF OPTICAL SENSORS

Abstract

Recent developments in fibre optics (FOs) and the myriad benefits of light over electronic devices has improved optical sensor usefulness as well as application in different military, industrial and social fields. Examples are environment and atmospheric analysis, earth and space research, synthetic chemicals and biotechnology manufacturing, law enforcement, digital imaging, scanning, and printing. The ubiquity of photonic technology may push costs lower, cutting the price of lasers and optical fibres. Fiber optic sensors (FOSs) deliver a large range of benefits, like small size and longer lifespan, over conventional sensing devices. Electromagnetic interference immunity, multiplexing capability, and high sensitivity enable FOs the sensor technologies of use in a variety of areas, such as the medical and aerospace industries. Over traditional electrical and electronic sensors, FOSs display efficient and rigid sensing duties. The analysis as well as the most useful uses for optical sensors are discussed in this article.
