Abstract

Interferometric visualization of the turbulent structure of a simulated high velocity mixing/shear layer has been achieved using a pulsed laser shearing interferometer. This technique has the advantages of being simple to implement, relatively insensitive to vibration, and capable of recording many interferograms during each test run. Visualization of the structure of these flowfields enables experimental determination of the turbule dimension, distribution, and relative spatial density. This makes possible the calculation of the correlation length and other flow parameters for more accurate experimental predictions of the aero-optic effects such as image jitter, boresight error, blur growth, and transmission loss.
