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 design of spectrum-dividing system is a key component of lidar. According to characters of DIAL, such as adjacency of laser wavelength and weakness of received signal, a set of optic fiber-grating spectrum-dividing system is developed. The system has the advantages such as high spectral resolution, efficiently divide lidar echo signals in different wavelengths, weak attenuation, receive and process signals in two channels synchronously, etc. So the SNR of receiving system has improved.
