Study on Measurement Errors due to Attenuation in Plannar Image technique

평면 이미지 기법에서 감쇠로 인한 측정 오차에 대한 연구

In the analysis of the mass distribution and SMD(Sauter Mean Diameter), planar laser imaging technique is a convenient and useful one when compared to the mechanical pattemator or PDPA (Phase Doppler Particle Analyzer). But recorded signals at cameras and intensity of laser are distorted by attenuation. Using experimental datum and assumptions, we study measurement errors due to attenuation in plannar image technique.
