Abstract
The method based on broad spectrum interference using femtosecond pulses is an important ranging method. In this paper, we experimentally evaluate the effect of interferometric spectral bandwidth used for calculation on the ranging results, and precision can be improved by choosing the optimal spectral bandwidth. In addition, in order to eliminate the influence of interferometric spectral fluctuations on the measurement results, we introduce the detrend algorithm into the processing algorithm and compare the measurement results before and after the algorithm improvement. Then, four kinds of nominal distance were measured and the contribution of the relevant factors to the measurement uncertainty is evaluated. Finally, the synthetic standard uncertainty of measurement results was 0.02 μm, 0.10 μm, 1.05 μm and 2.78 μm for nominal distance of ~0 m, ~1.5 m, ~16.5 m and ~43.5 m respectively.
期刊介绍:
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
