Overview of Fiber Optic Sensors Abstract: With the development of optical sensor technology, fiber optic sensor has the advantages of resistance to electromagnetic interference, corrosion, resistance, excellent insulation, wide measuring range, easy for multiplexing, solving problems that other sensors cant solve, etc, these sensors as one of the faster-developing technology are widely applied in the field of civil engineering, aerospace, electric power, medical treatment, shipbuilding industry, and so on. In this paper, we study the basic knowledge on optical sensor technology. Keywords: fiber optic; fiber Bragg grating; optical fiber sensor 1. Introduction Optical fiber sensor is developed at the end of 70s as a new type of sensor, it has not affected by electromagnetic field effect, in essence safety explosion-proof, small size, corrosion resistance, the advantages of high sensitivity. Used in traditional sensor is difficult to set foot in the extreme environment, so in the military, aviation, biological medicine, building construction field is popular. So to optical fiber sensor research has very important practical significance. Sensing technology is popular in recent years, the application of the technology in the sensitive, accurate sensor, strong adaptability, cabinet and wisdom of the direction of development. In this process, optical fiber sensors the sensor to the new members of the family is extremely popular. Optical fiber has many excellent properties, such as: the electromagnetic interference and atomic radiation performance, diameter is fine, soft and light weight of mechanical properties, insulation, without induction electrical properties, water resistant, high temperature resistant and corrosion resistance of the chemical properties, it can not reach people places (such as high), or harmful to the person of the area (such as nuclear area), plays the role of the refreshing, and still can transcend boundaries, receiving of physiological the sense
