A Sandia National Lab team has developed a new optical device that helps researchers image pollutants in combusting fuel sprays that might lead to clearer skies in the future.
The optical setup can now quantify the formation of soot – particulate matter consisting primarily of carbon – as a function of time and space for a variety of combustion processes.

The optical setup was developed by researchers at Sandia’s Combustion Research Facility and the Technical University of Denmark. Initially, the researchers had focused on the combustion of liquid fuel sprays found in engines, where the extreme pressures and temperatures create an environment that is optically challenging.
