Sprays are among the most intellectually challenging and practically important topics in fluid
mechanics. This paper reviews needs, milestones, challenges, and a broad array of …

A review is presented of measurement techniques to characterise dispersed multiphase
flows, which are not accessible by means of conventional optical techniques. The main …

Multiple ultrashort laser pulses are widely used in optical spectroscopy, optoelectronic
manipulation, optical imaging and optical signal processing etc. The laser pulse …

Imaging through optically dense sprays is challenging due to the detection of multiple light
scattering, which blurs the recorded images and limits visibility. Structured laser illumination …

In imaging, the detection of light originating from multiple scattering, indirect reflections and
surrounding backgrounds are known to produce errors especially in intensity-ratio based …

We report in this Letter a two-phase structured laser illumination planar imaging [two-pulse
SLIPI (2p-SLIPI)] optical setup where the “lines structure” is spatially shifted by exploiting the …

Abstract Conducting CH 2 O PLIF imaging in scramjets is challenging due to strong flame
emissions (FEs). The FE interference is comparable to the CH 2 O fluorescence in the …

Fluorescence lifetime determination has proven to be useful, eg identification of molecules,
quantitative estimation of species concentration and determination of temperatures. Lifetime …

We show in this Letter a novel approach for high-contrast imaging through scattering media
by combining structured illumination and Fourier filtering (SIF). To assess the image contrast …

Ammonia fuel is expected to contribute not only to the decarbonization of society but also the
stabilization of the global energy situation. Liquid ammonia (LNH 3) spray combustion is an …
