Detector of Optical Vortices as the Main Element of the System of Data Transfer: Principles of Operation, Numerical Model, and Influence of Noise and Atmospheric Turbulence

Table 2

Influence of optical axes shift 𝑆_ℎ𝑥 and outer scale 𝑀_outer of turbulence on difference 𝐼_𝑟0max−𝐼_𝑟1min and mean difference ⟨𝐼_𝑟1−𝐼_𝑟0⟩ of functions 𝐼_𝑟1(𝑁_𝑟) and 𝐼_𝑟0(𝑁_𝑟).

Difference	Shift of axes 𝑆ℎ𝑥/𝑟0𝐵				Outer scale of turbulence 𝑀outer/𝑟0𝐵
	0	0.315	Increase: 0→0.315		5	20	Increase: 5→20
