| description | PROBLEM TO BE SOLVED: To provide a measuring method and device which can measure an aerosol particle diameter and speed in real time without affecting the free flow when measuring a particle speed of an aerosol free flow, such as aerosol spouting out from a nozzle to the air, and a composite structure manufacturing device using the measuring device. SOLUTION: In the present invention, a laser 6 is irradiated from a laser projecting part 2 to the aerosol 5, a camera 4 takes images of the light diffracted and scattered by the projected laser, and then the aerosol particle diameter and speed is measured from the particle locus of the images taken. The particle diameter and speed are calculated from the width of the particle locus, and the length of the particle locus and the exposure time, respectively. Therefore, the aerosol particle diameter and speed can be measured without affecting the free flow of the aerosol flowing in the air with this method. COPYRIGHT: (C)2005,JPO&NCIPI |
