| 摘 要： | 由于重力场、温度场、光学器件等产生波前误差,造成航空详查相机的分辨力和测量精度降低,用自适应光学钠导星信标系统对这种波前误差进行校正是一种理想的方法。通过对钠导星信标产生原理进行分析,提出了钠导星信标理论模型,并且在该模型的基础上进行了仿真实验,在实验中得到相机高度在250-400km高空时激光器最佳脉冲能量值在597-1530mJ之间,激光脉宽则在5.4-7.1ns之间,这些实验数据对实际应用有一定的参考价值。

| Abstract: | The resolution and measuring accuracy of aerial surveying camera will be lowered by wave- front errors generated in gravitational field, temperature field and optical devices. Correction of the wave-front error in an adaptive optical system with Na guide-star beacon is an ideal method. A theoretical model for Na guide-star beacon is proposed through analyzing the generating principle of Na guide-star beacon and simulation experiments are carried out on the model. The optimal laser pulse energy value within a range of 579-1530 mJ and a width within a range of 5.4-7.1 ns are obtained from experiments with camera operating at an attitude of 250-400km. These experimental data have some reference value for practical application. |
