Laser induced fluorescence method was applied for the visualization of Volatile Organic Compound (VOC) gas. Fourth-harmonic generation light of ND : YAG laser was used for the excitation of the VOC gas. An image intensifier (I/I) was used for capturing the VOC fluorescence images. Diffusion characteristics of VOC from suspended droplets of xylene and toluene were investigated. Moreover, VOC images from a droplet deposited on a wall and a spray flow were visualized by this method. Measurement results were compared with the solutions of the one-dimensional diffusion equation. As the result, it was confirmed that the diffusion phenomena could be analyzed by the LIF method.

采用激光诱导荧光法对挥发性有机化合物（VOC）气体进行可视化。采用Nd：YAG激光器的四次谐波产生光激发VOC气体。图像增强器（I/I）用于捕获VOC荧光图像。研究了二甲苯和甲苯悬浮液滴中VOC的扩散特性。此外，VOC图像从沉积在墙上的液滴和喷雾流可视化通过这种方法。测量结果与一维扩散方程的解进行了比较。结果，证实了扩散现象可以通过LIF方法进行分析。
