In this work, we estimate the atmospheric Fried parameter r_0 r_0, average wind speed ̄v
v¯, and subsequently, atmospheric coherence time τ_0 τ_0 by experimental measurement …

Free Space Optical Communication (FSOC) is a wireless communication method that
utilizes laser beams for high speed and secure data transmission. Its performance is affected …

We report on an analytic method to estimate the Fried parameter r_0, average wind speed
v¯, and subsequently the atmospheric coherence time τ_0 via a 4-aperture differential …

The present paper introduces a method for measuring the atmospheric coherent time which
is based on Fast Defocus method (FADE). The configuration of the system is modified in …

The present study aimed to evaluate the ability of the 4-and 8-aperture Hartmann method to
calculate atmospheric primary aberrations. In the 4-aperture Hartmann screen, the holes can …
