摘要：
A basic concept for detection and identification of liquid phase chemicals that may harm the environment is presented. Reliable detection is shown to be possible using a simplified model describing a uniform layer as well as realistic dispersal, shown to be in nonuniform irregular surface coverage. The results are dependent upon the effect of droplet size and spectral scattering from liquid-air interface on the measured scattered light. This information is crucial for accurate identification for on-site real-time sensing. (C) 2019 Society of Photo-Optical Instrumentation Engineers (SPIE)
