China is the world, the most populous country, so the demand for electric power is very large. With the rapid development of economy, intelligent systems in various scientific fields have been widely popularized, and sensors play an important role in intelligent systems. Traditional sensors have a single perception function, and with the continuous development and innovation of technology, people give sensors more new functions to solve difficult problems encountered in practice. This paper focuses on optical fiber sensor, discusses its specific application in new energy, and summarizes the principle and significance of optical fiber sensor itself.

The laser displacement sensor, profile scanner, spectral confocal sensor, capacitance sensor and eddy current displacement sensor are widely used in all aspects of intelligent equipment detection. For example, the display detection of smart equipment is usually very difficult, because modern displays are usually composed of multiple layers of transparent substances, and the thickness detection of each layer of substances is very difficult. The spectral confocal displacement sensor provided by the German Miridium company, due to its special measurement principle and exquisite manufacturing technology, can detect transparent layers of different textures at one time, obtain multi-layer thickness parameters, and will contact the display under test to avoid secondary damage during the detection process. Its ultra-high detection efficiency also meets the needs of modern large-scale production.

Looking at the future sensor market, high-performance, multi-functional, intelligent, and integrated will become an inevitable development trend. From the perspective of application fields, industrial automotive electronics, communication electronics, and consumer electronics are the largest market for sensors. Sensors in the field of domestic industrial and automotive electronics account for about 42%, and the fastest growing market is automotive electronics and communication electronics applications.
