Portal hyperspectral imaging system for application in real-time detecting waster-water

Aim at existing measurement problems of biochemical oxygen demand (BOD), this paper presents a new detection method of waster-water based on hyperspectral imaging technique. The method provides image and spectral information at the same time by the real-time hyperspectral imaging of appointed water area, so it can achieve for BOD qualitative, quantitative and location analysis with appropriate identification method. It is a rapid and simple detection method, which provides a new approach to real-time detection of BOD.
