We measured soot concentration by laser-induced incandescence (LII) in diesel exhaust gas. We used a compact Nd: YAG laser. The laser is small and portable, applicable for measurement in outer field. LII signals were recorded by a ICCD camera. To obtain absolute soot volume fraction, laminar diffusion flames stabilized on co-annual burner were used in calibration process. Results show that the monitored pressure becomes larger as the engine rpm increases. To compare soot concentration with and without diesel filter, it is confirmed that the soot concentration in exhaust gas is reduced when the diesel filter is used.
