Abstract: A high precision fiber-optic device and method are developed for measuring a temperature profile in a long length area.

Controlling the output power of the of the amplified pulsed optical radiation is carried out based on a feedback representative of the intensity level of the anti-Stokes Raman component of the optical radiation back scattered from the reference optical fiber.
