| Outline of Final Research Achievements |
Laser-induced breakdown method is the only way that can measure the absolute number density of droplets in aerosol. However, this measurement method requires a large number of laser shots. Moreover, enormous measurement points are required for a spatial density distribution of aerosol. A technique of the density measurements at multiple points simultaneously is essential way to be shortened the measurement time for density distribution. A laser beam is divided into 6x6 beams by a DOE (Diffractive Optical Elements) and focused by a plano-convex lens on lattice-shape. Each breakdown at the multiple measurement points is observed by a camera system. Actual density distribution of aerosol ejected from a spray nozzle is observed plausibly by this system. This measurement system reduces the measurement time for the density distribution of droplets in an aerosol effectively.
