= Filtered Rayleigh Scattering =

Filtered Rayleigh scattering (FRS) is a laser-based flow diagnostic technique that may be applied to systems to allow the measurement of various gas properties including density, temperature, and velocity. By using a selective, narrow-linewidth frequency filter in conjuction with a tunable, narrow-linewidth laser, changes in the spectral features of scattering can be directly imaged. This technique allows temporal and spatial resolution of gas properties for a number of interesting systems.

Applications
1. Density measurements

2. Temperature measurement 3. Velocity measurement (utilizing the doppler effect)
