Although one may jump right into optical measurements without more knowledge of optics than provided in basic engineering or natural science courses, optical methods for flow diagnostics are commonly known to be some of the more treacherous and difficult measurements to apply in pr

Principles of Laser Anemometryld be called modern laser anemometry goes back to the measurements of Yea and Cummins.. They performed a light scattering experiment on small particles suspended in a fluid pipe flow. Light scattered in a given direction would exhibit a well-defined Doppler shift. The shift is generally too small to

Several investigations have been performed in PTB as to measure flow profiles without scanning the sensor, to acquire the instantenous velocity vector using only one source, to sense the direction of flow by passive frequency shifting using Brillouin scattering, or, active by matching two Nd: YA

The measurement region may be defined by a thin laser sheet (a 2-D cross section of the flow) or by illumination of an entire volume (a complete 3-D flow f
