Description	Mie-scatter and combustion chemiluminescence and soot luminosity are visible. Mie-scatter luminosity is out of focus because of the low f/# needed to simultaneously collect combustion luminosity. Soot luminosity background is dynamically corrected.	With laser off only combustion chemiluminescence and soot luminosity are visible. Flame clearly exists at the injector after the end of injection, and soot luminosity forms from poorly mixed, but vaporized, fuel (no Mie-scatter is visible there is no laser illumination).	Schlieren movie obtained simultaneously with Mie-scatter movie. Flame border overlaid. Schlieren movie shown with and without corrections for background schlieren effects from the ambient. Soot luminosity adds to the schlieren light because of broadband light collection.	Schlieren movie obtained simultaneously with luminosity movie. Flame border overlaid. Soot luminosity now not visible in schlieren because of bandpass filtering.
