Abstract
Velocity measurements based on the transport of turbulence induced refractive index structures are investigated. Particle scattering is assumed to be negligible. The scattering from collective structures is analyzed with a phase screen model. A system based on reference beam detection and combining Doppler and time-of-flight concepts may provide the best spatial resolution and utilize a broad band region of the high frequency turbulence for light scattering. In the optical region it is so that a long wavelength is preferable and reference beam detection is necessary. An potential hybrid system for plasma diagnostics is presented. It is shown that time resolved measurements may be possible.
