摘　　要：针对测量粒径的传统傅里叶测量系统(FS)的缺点,提出了一种改进的逆傅里叶激光测量系统(RFS)。通过实验测量,结果表明通过增加散射体与透镜的距离可以增加粒径测量的下限,扩大粒径测量的范围。另外,还对不同粒径的测量结果和理论计算结果进行了对比。结果表明,该方法特别适合于在小颗粒的测量。For measurements on particle size, an improved reverse Fourier laser measurement system（RFS）which based on disadvantage traditional Fourier system（FS） is presented. In the experimental parts, the results show that the increase in lower limit of particle size measurement by increasing the distance of scattering volume and lens can expand the range of particle size measurement. In addition, the different particle size measurement results and theoretical calculation results are compared. The experimental evidence and simulation results show that, this method is especially suitable for measuring small particles.
