一、光纤传感器随着技术革命的兴起,传感器已成为与微型计算机具有相同地位的重要技术工具。国际上许多科学家与实业家把八十年代称为“传感器时代”。当前,传感器的研制工作十分活跃。为了促进我国传感器技术的发展,本文着重介绍日本光纤与家用温度传感器的动向及气敏传感器的应用。应用光的干涉、衍射、偏光、反射、吸收及发光等特性的光测技术,作为非接触、高速、高精度的检测手段,自1960年发现激光以来取得了飞速进展。最近,为了将低损耗的光纤及半导体发光元件引入各种光学测量,已做了大量研究工作。光纤测试技术民的最大优点是:探头可以逼近但又不触及被测对象,可在高压、强磁场、爆炸性气氛等恶劣 First, the optical fiber sensor With the rise of the technological revolution, the sensor has become an important technical tool with the same status as the microcomputer. Many international scientists and industrialists called the 1980s the “sensor era.” At present, the development of the sensor is very active. In order to promote the development of sensor technology in our country, this article focuses on the trends of Japanese optical fiber and domestic temperature sensor and the application of gas sensor. As a non-contact, high-speed and high-precision detection method, the optical measurement technology using the characteristics of light interference, diffraction, polarization, reflection, absorption and light emission has made rapid progress since the laser was discovered in 1960. Recently, a great deal of research work has been done to introduce low-loss optical fibers and semiconductor light-emitting elements into various optical measurements. The biggest advantage of optical fiber testing technology is: the probe can be approached but does not touch the object under test, in the high pressure, strong magnetic field, explosive atmosphere and other harsh
