摘要
描述了一种使用调q激光器作为拍摄喷雾中液滴的光源的方法。被喷液体中的荧光染料被3471 A的红宝石光的二次谐波激发。小至10 μm的液滴以高达50 m / s / 1的速度运动，成功地拍摄到了这些液滴。动态尺寸校准表明，从喷雾照片中可以获得可靠的液滴尺寸信息。
Fluorescent photography of droplets in a spray using a Q-switched laser as a light source
A method of using a Q-switched laser as a light source for photographing droplets in a spray is described. A fluorescent dye in the liquid being sprayed was excited by the second harmonic of ruby light at 3471 A. Droplets as small as 10 μm, travelling with velocities as high as 50 m sec-1, were successfully photographed. A dynamic size calibration showed that reliable drop size information could be obtained from the spray photographs.
