Optical sectioning for measurements in transient sprays

Artikel i vetenskaplig tidskrift, 2016

We describe a practical arrangement for optical sectioning by means of time-gated backscatter imaging using ultrafast illumination and a CS2-based optical Kerr effect shutter. This arrangement can reveal additional information when probing transient turbid media such as fuel injection sprays or complex multiphase flows which require single-shot imaging with sufficient time resolution to freeze the dynamics of the flow.
