Soot is considered a hazardous pollutant emission and is typically a result of incomplete combustion processes, and thus is also related to combustion performance. Laser Induced Incandescence (LII) is a laser-optical measurement technique dedicated to soot diagnostics. LII can provide measurements of soot volume fraction, such as in Diesel engine exhaust, and even instantaneous images of soot distribution during formation inside a running IC engine.
