实验结果表明，该方法可有效地突破最大物参角的限制，同时可以消除由于欠采样造成的频谱混叠现象。

The experimental results show that the method can overcome the limitations of the critical angle between the object and reference beams, and omit the frequency aliasing.

根据星地激光通信的实际状况，对接收孔径的归一化到达角起伏频谱进行了讨论。

In this paper, we talk about the collection aperture's normalized arrival-of-angle fluctuation spectrum in Satellite-ground laser communication.

当入射光束频谱为三角形函数时，我们用计算机计算了透过F - P标准具以后的频谱分布。

In case the spectrum of incident beam is a function of triangular form, we calculated the spectral distribution of transmission through the F-P etalon with a computer.
