摘要

分析预算链路和自由空间光学系统的性能需要计算受大气湍流影响的采集光的多个指标。在这项工作中，假设收集到的光聚焦到光纤中或聚焦到位于焦平面的传感器上，我们使用 ABCD 射线矩阵表示法来计算大气湍流对光纤中功率或传感器上功率的影响。计算此类指标需要了解进入接收器孔径的传输平均功率（桶内功率）和焦平面内的长期光束扩散，并由此获得施特莱尔比。

Focal plane analysis of optical power-related metrics for atmospheric turbulence-affected laser beams

The analysis of budget link and free space optical system performances requires the calculation of several metrics of the atmospheric turbulence-affected collected light. In this work, assuming the collected light is focused into an optical fiber or over a sensor positioned in the focal plane, we use the ABCD ray-matrix representation to calculate the impact of atmospheric turbulence on the power in the fiber or power over the sensor. Calculation of such metrics requires the knowledge of the transmitted average power that enters the receiver aperture (power in the bucket) and the long-term beam spread in the focal plane, from which the Strehl ratio can be obtained.
