High Resolution Optical Temperature Sensor

LDT-100 high resolution optical temperature sensor measures the temperature profile across standard optical fibers. The measurement technique is based on Raman scattering. Due to the temperature dependence of the Raman scattering signal (Anti-Stokes) temperature variations along the sensing optical fiber are transformed in a variation of the backscattered signal. The LDT-100 uses photon-counting technology to achieve a high detection efficiency and very high spatial resolution. An internal temperature calibration reference makes the system ready for testing and minimizes time consuming user re-calibration.
The LDT-100 also integrates OTDR testing capability which allows integrity and condition testing of the sensing optical fiber.
The LDT-100 is a fully portable, simple and easy-to-use instrument, with user-friendly GUI software.
A desktop version with USB interface is available as an option.
