<p>Laser induced incandescence (LII) has been the most commonly used technique for measurement of soot primary particle size and soot volume fraction in combustors, engine exhaust gases, and ambient atmospheric environments. Unlike other soot detection techniques that need soot sampling process, LII is in-situ measurement in which thermal radiation from soot particles heated by a pulsed laser is detected to evaluate soot particle temperature or soot volume fraction. In this article, fundamentals of LII measurement are described for better understanding of its principle, in particular with time-resolved two-color LII, highlighting recent progress in LII models. In addition, combination of LII and elastic laser scattering is introduced as a challenging technique providing information on aggregation of soot particles.</p>
