This paper proposes to use the model of cladding particle scattering to construct the attenuation of haze aerosol, and use PM2.5 index to characterize the haze intensity. When the laser is transmitted along any path, the attenuation of the oblique path is divided into micro path by using the layered calculation idea of calculus. Since the micro path can be equivalent to the horizontal path, the attenuation of any path can be obtained by integrating the attenuation of each microscopic path. The error between the numerical results and the Kruse model is only 3.69% at haze case. In the international meteorological standard, the error within 5% means that the calculation result is valid.Then, according to different relative positions of coherent wind lidar and atmospheric wind field, they can be divided into three cases. Finally, the effects of haze weather with different intensity on the detection power, carrier noise ratio and wind speed measurement accuracy of the coherent wind lidar are analyzed under three different relative positions.The simulation results show that the increase of PM 2.5 index will reduce the effective range of the wind lidar. The PM 2.5 index of the system is no more than 554 and the limit of CNR is -11.4dB and estimation accuracy is 0.005m/s when the propagation distance is 1km on ground. The degree of limit value can become smaller via increasing system altitude and decreasing zenith angle.

In recent years, underwater wireless optical communication (UWOC) has attracted more and more attention owing to its high bandwidth and high speed. The blue-green band is a transmission window due to its relatively low loss in the underwater channel. However, UWOC is still limited to about 300 meters subjecting to the large channel loss and the mediocre sensitivity of the avalanche photo-diode (APD). In this paper, we propose and experimentally realize an underwater optical communication scheme based on single-photon detection and non-return-to-zero on-off keying (NRZ-OOK) modulation. The key rate of 200 kbps was achieved with a bit error rate (BER) of 1×10⁻⁴ below the forward error correction (FEC) limit of 3.8×10⁻³ with 7% overhead when the power of the light source is 0.02 mW and total channel loss is 67 dB. The relatively good result shows that a system adopting an NRZ-OOK modulation scheme and single-photon detection is promising for high bandwidth and long-distance underwater optical communication.
