Abstract:

The intensity fluctuations and image jitter of a laser beam propagated through a twisted high-temperature flame jet, as well as fluctuations of the optical radiation emitted by the flame itself, are studied experimentally. Alcohol in an immovable vessel was used as a fuel. In some experiments, the vessel was filled with brass filings. The flame was twisted with a fan, installed over the vessel. The frequency spectra of fluctuations were determined as functions of the fan's speed of rotation.
