OPTICAL FIBER SENSING
 BOTDR Method
 
High reliability against noise and lightning!
Turning from measurement of points to measurement of planes!


We are developing measuring instruments using optical fibers. This is based on the measurement principle that the frequency of Brillouin scattered light (Fig. 1) changes when distortion occurs in optical fiber and that the amount of distortion can be detected. (Fig. 2) by measuring the shift.

Measurement principle






A great number of sensors are being developed by this method,
including the types of sensors shown in the following figure.


Joint development products with NTT Neomeit Co., Ltd.


We possess a track record and know-how in development
of a great number of unique sensors by the BOTDR method
