| 摘 要： | 运用湍流大气的Andrews折射率谱近似模型从理论上分析了大气成像系统的光学传递函数并研究了有限湍流尺度 (湍流内、外尺度 )对湍流大气中成像系统光学分辨率的影响。结果表明应该考虑湍流尺度对大气系统成像的作用。采用近似Andrews折射率谱模型所得结果与采用纯指数谱计算结果有明显差别。

| Abstract: | The OTF of the atmosphere imaging system is calculated and the effects of the scale of turbulence on the integral resolution are analyzed by using the approximate Andrews model of refractive index fluactuation. The results obtained for the approximate Andrews modle turbulence spectrum significantly differ from those obtained for a pure power law turbulence spectrum. |
