Laser-Induced Incandescence

Soot is considered a hazardous pollutant emission, and is typically a result of incomplete combustion processes and is thus 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 in e.g. Diesel engine exhaust and even instantaneous images of soot distribution during the formation inside a running IC engine.
