Abstract

The present investigates the atmospheric Fried parameter, r0, a critical measure of the strength of optical turbulence. As part of my research, a dedicated measurement system was designed, built, and deployed. Situated on a test field, the system operated autonomously, collecting data and providing real-time atmospheric measurements. Simultaneously, the data was processed and a comprehensive comparison of the various measurement methods used was conducted.
The new device combines several measurement methods: Full Width at Half Maximum (FWHM) astronomical seeing, image motion, differential image motion (DIMM), and scintillation. A major focus of this study was the design, construction, and validation of the measurement system, which was developed specifically for this research.
The main objective of this study is to develop a measuring system to estimate Fried parameter using multiple methods in a single one-sided device. Such a system could be positioned outside during field experiments and supplies real-time view of the atmospheric conditions.
This study demonstrates the feasibility and benefits of utilizing a single device capable of measuring Fried parameter by multiple techniques. Using this integrated approach a more comprehensive understanding of turbulence characteristics is achieved while minimizing resource demands.
