Paper Abstract

Differential Absorption Lidar for detecting atmospheric NO2 (NO2-DIAL) is used extensively for its high precision and spatial resolution, and the measurement can be done real-time with a wide range. The uniaxial crystal reflectivity must be considered in optical path adjustment. From the point of view of energy, based on optical electromagnetic theory and Jones matrix, the relationship between intermediary reflectance and polarization state of incident light is discussed, and the normal relational expression of them is gained. An experiment example is given, and the measured value of the example is in conformity with the computer simulation curve. The result shows that the regulation of crystal reflectivity has useful significance for adjusting the optical path of NO2-DIAL.
