OSI-D

Description

The principle of Semicon OSI-D is based on optical frequency domain reflection (OFDR), which has the characteristics of high precision and high spatial resolution. Systems combining dynamic algorithms, high-speed demodulation is obtained. And single-mode optical fiber as sensors are low-price to purchase and easy to install.

One scan simultaneously measure more than thousands of sensing points along a single fiber. OSI-D is quite an useful tool for dynamic distributed strain and temperature measurement.
