A numerical S/N estimate, which is based on the S/N theory of a PMT(Photo-multiplier tube), in measuring aerosol particles by an ICCD camera was proposed for designing an optimal optical system. In this estimate, two coefficients were newly introduced to take account of both the light accumulation and the exposure time of the ICCD camera. The accuracy of this estimate was investigated experimentally for several particle sizes from 0.1 μm to 0.5 μm. We could easily measure the particles in an area about 46 mm× 15 mm, and the S/N estimations agreed with the experimental results about 5 %. Therefore, it was made clear that the estimate is very useful to design the 2-bimensional particle measuring system with the ICCD camera.
