自由空间基本传输损耗 free space basic transmission loss
这样，当光束继续在自由空间传输时，能保持其形状不变。
Thus, they can retain their shape unchanged upon further free-space propagation.
由于电信号传输系统保密性和抗干扰能力差，为此，利用声光晶体的衍射效应研制了一种光信号自由空间传输系统。
To resolve this problem, a free space transmission system for optical signals is developed on base of diffraction effect of acoustooptic crystal.
对其通过自由空间和付里叶变换系统特殊情况的传输作了分析和讨论。
Free space propagation and Fourier transfer system are also analyzed and discussed as particular cases.
