摘要

The soot concentration measurement system based on the scattering integral method has more advantages. However, the poor optical path alignment will directly affect the measurement accuracy. The measurement error caused by the poor optical path alignment of the measurement system is analyzed. For the measurement system, a new type of optical path adjustment method is brought out which is divided into two parts: coarse and fine adjustment. A new type of four-quadrant photoelectric sensor is designed to adjust easily optical path. Experimental results show that the optical path alignment method can improve the precision of optical path adjustment and reduce the soot concentration measurement error.
