【Abstract】 Current work presents a method to measure the smoke particle size distribution by the near-forward scattering light of laser sheet based on Mie scattering theory. An algorithm to correct the image deformation using DLT method was brought forward. The particle size distributions of several types of fire smoke were measured and one of the results was analyzed. Some error-causing factors were discussed. 更多还原
