Laser techniques of measuring particles size and their size distribution

Yang Ye; Zhang Zhenxi; Jiang Dazong

According to the characteristics of fuel spray,CBP (Convolution backprojection),ART (Algebraic reconstruction technique) and SIRT (Simultaneous iterative reconstruction technique),which are used to realize the visualization of the internal structure of fuel spray,are studied in this paper.The reconstruction results with a P540 digital image processing system show that when the noise exists in the projection data,the SIRT provided the best image reconstruction taking the longest calculation time,the worst image reconstruction is obtained by CBP taking the shortest calculation time,and ART is in the middle.
