In their latest publication “Doppler optical frequency domain reflectometry for remote fiber sensing, Max Köppel and Jasper Podschus present a new method for fiber sensing.

Using this technique, they were able to perform high-resolution distributed temperature measurements. To do so, optically levitated particles are tracked inside a hollow-core photonic crystal fiber.

Max and Jasper work at the Institute of Microwaves and Photonics (LHFT), supervised by Bernhard Schmauss. The original publication can be found in Optics Express.
