And to start with the analysis of total receiving energy on the detector, the amount of the noise energy produced by background light is discussed and calculated detail when using VUV filters as the filters of the system, so that it is proved the feasibility of applied.
针对卫星间直接光学通讯的特点，分析了所需滤波器的特性，提出用真空紫外滤光片作为卫星间光通讯系统滤波器，并从对探测器上所接收到总能量的分析入手，详细讨论并计算了用真空紫外滤光片作为该系统的滤波器时，背景光所产生的噪声能量大小，从而证明了在卫星间直接光通讯系统中应用真空紫外滤光片是可行的。
