평면 이미지 기법에서 감쇠로 인한 측정 오차에 대한 연구

Study on Measurement Errors due to Attenuation in Plannar Image technique

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.
