Application of a stepped acousto-optic deflection technique to interferometric photography
TLDR
This work combines the technique of stepped acousto-optic defection with a laser interferometer to construct a new high-speed and multiframe interferometric photography instrument and uses it to record time-sequence interferograms of a transient combustion field.Abstract:
We present the application of a stepped acousto-optic deflection technique to interferometric photography. We combine the technique of stepped acousto-optic defection with a laser interferometer to construct a new high-speed and multiframe interferometric photography instrument and use it to record time-sequence interferograms of a transient combustion field. Furthermore, on the basis of these interferograms, we calculate the temperature variations of the field with time quantitatively.read more
