The Rytov number is a fundamental scaling parameter for laser propagation through atmospheric turbulence. Rytov numbers greater than 0.2 are generally considered to be strong scintillation. A Rytov number of 0 would indicate no turbulence, thus no scintillation of the beam.
Famous quotes containing the word number:
“Cole’s Hill was the scene of the secret night burials of those who died during the first year of the settlement. Corn was planted over their graves so that the Indians should not know how many of their number had perished.”
