Abstract

When laser light propagates though the atmospheric turbulence, it would be affected by the fluctuation of atmospheric turbulence. Especially in harsh environments, atmospheric fluctuation will cause serious dispersion of the light spot, which has a serious impact on the energy utilization rate of laser eavesdropping system. This study focuses on the relationship between temperature fluctuation and energy utilization rate of laser eavesdropping system via the numerical simulation. Taking the temperature pulsation meter type QHTP-2 as the example, the theoretic derivation and numerical simulation are conducted. The result shows that the average energy utilization rate decreases rapidly with the increase of the standard deviation of temperature, and the 15% measurement uncertainty of the temperature pulsation meter will cause the energy utilization rate fluctuation between -6% and 8%. It provides us with a valuable criterion for laser eavesdropping system design.
