Distance measurement in air without the precise knowledge of refractive index fluctuation
Morris Cui, Steven A. van den Berg, Nandini Bhattacharya
The accuracy of long distance measurement in air is limited by the fluctuation of refractive index. In this paper, we propose a technique which allows us to measure an absolute dis…
