各种光纤传感器正在稳步地进入传感器市场。目前重点在于工业或工程型温度、压力,位置、流量和液位传感器的商品化。温度和压力传感器约占现有市售传感器产品的40%,其中大部分产品专门用于医学和化学方面;液位传感器占12%;位置和与之相似用途的传感器亦占12%;化学和生物传感器占8%;加速度传感器占8%;其他类型传感器,诸如折射、转矩、旋转、速度、电场、辐射、气体-密度传感器,占17%。目前市场上的大多数光纤传感器是利用以强度为基础的传感技术,而商用干涉传感器可望于最近的将来问世。 Irvine(加利福尼亚州)的Cardiovascular器件公司正在销售一种25密耳直径“光电极”传感器,它可
Various optical fiber sensors are steadily entering the sensor market. The current emphasis is on the commercialization of industrial or engineering temperature, pressure, position, flow and level sensors. Temperature and pressure sensors account for about 40% of existing commercially available sensor products, most of which are used for medical and chemical purposes; liquid level sensors account for 12%; sensors for positions and similar uses account for 12%; chemical and Biosensors account for 8%; accelerometers account for 8%; other types of sensors, such as refraction, torque, rotation, velocity, electric field, radiation, gas-density sensors, account for 17%. Most fiber optic sensors on the market today make use of intensity-based sensing technology, and commercial interferometric sensors are expected to come out in the near future. Cardiovascular Devices of Irvine, Calif., Is shipping a 25 mil diameter “photoelectrode” sensor that can
