Abstract

We propose a single shot BOTDA based on optical chirp chain and image denoising. By employing polarization diversity and image denoising technique, the need of trace averaging is avoided. Single shot measurement of temperature over 10 km single mode fiber is achieved. The spatial resolution and BFS uncertainty are 6 m and 2 MHz respectively.
