Method of Estimation of Turbulence Integral Parameters

Applied Sciences, 2021
The optical effects of turbulence are directly related to turbulence integral parameters, which are integrals of the refractive index structure constant over a whole path with different path-weighting functions (PWFs).

Analysis of Optical Turbulence over the South China Sea Using Balloon-Borne Microthermal Data and ERA5 Data

Remote Sensing, 2022
It is very useful for adaptive optics (AO) systems to have appropriate knowledge of optical turbulence. However, due to the limitations of space and time, it is difficult to obtain turbulence parameters, especially in the far sea area. In this paper, the

Turbulence Time Series Data Hole Filling using Karhunen-Loeve and ARIMA methods [PDF]

, 2007
Measurements of optical turbulence time series data using unattended instruments over long time intervals inevitably lead to data drop-outs or degraded signals.

Measurements and Modeling of Optical Turbulence in the Coastal Environment

Applied Sciences, 2022
The goal of this study was to characterize optical turbulence in the near-coastal environment. Measurements to obtain the refractive index structure parameter and other meteorological data were taken over the course of a month along the shore of Monterey

Optical intensity interferometry through atmospheric turbulence [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
Conventional ground-based astronomical observations suffer from image distortion due to atmospheric turbulence. This can be minimized by choosing suitable geographic locations or adaptive optical techniques, and avoided altogether by using orbital platforms outside the atmosphere.
