最近日本“竹中电子工业公司”研制成功一种F M 系列超小型光学纤维传感器。这种传感器有五个类型,其主要特点是它的放大部分和光学纤维分开放置,因而它适用于测量空间很小的地方;另外由于有的类型的传感器带有防水结构,所以它可用于恶劣环境中,并且测量稳定。其主要规格是,测量距离为30、20、10 mm Recently, Japan’s “Takenaka Electronics Industrial Co., Ltd.” successfully developed a F M series of ultra-small optical fiber sensors. This sensor has five types, its main feature is its enlarged part and the optical fiber placed separately, so it is suitable for measuring small space; and because some types of sensors with waterproof structure, so it can be used for harsh Environment, and the measurement is stable. The main specification is that the measuring distance is 30, 20, 10 mm
