Incoherent detection of airborne pollutants
WebIndoor levels can vary from 10% of the outdoor air to levels as high as 80% of the outdoor air. The Food and Drug Administration has set a limit of 0.05 ppm of ozone in indoor air. In recent years, there have been numerous advertisements for ion generators that destroy harmful indoor air pollutants. WebRemote Sensing. Lidar uses a laser source to illuminate a subject and sophisticated. sensor technology to analyze the reflected radiation or light. scattered from the subject. This technology is adaptable to. a range of material size, from microscopic particles to large. landmasses, as well as density, from atmospheric gases. to complex compounds.
