In this Letter, we utilize the speckle model to measure the average random scattering rate of fiber backscatter and analyze its dependence on length, yielding a linear fitting coefficient of 0.23 ppm/m for a PM980-XP fiber. We incorporate the temperature coupling effect into the model and validate the model's accuracy by examining the distribution of the change rate of the backscattering rate relative to the temperature and the amplitude spectral density of the backscattered power.

- Optical path length (OPL) noise from stray light limits interferometry measurements in low frequencies.
- This paper develops an analytical model to analyze stray light's impact in heterodyne laser interferometers.
- A noise suppression strategy is introduced that stabilizes stray light OPL at a specific point, resulting in a dramatic reduction in displacement noise to below 6 pm/Hz at frequencies as low as 1 mHz.
Room-temperature sodium-sulfur (RT-Na-S) batteries are attracting increased attention due to their high theoretical energy density and low-cost. However, the traditional RT-Na-S batteries assembled with glass fiber (GF) separators are still hindered by the polysulfide shuttle effect and sodium dendrite growth, limiting the battery's capacity and cycling stability. Here, a facile and effective method toward commercial polyolefin separators for constructing stable RT-Na-S batteries is presented.
