Pallé says that this characterization will be done best by capturing a planet's transmission spectra rather than by trying to capture starlight reflected by the planet's atmosphere.

Palle说，如果通过捕捉行星的透射光谱来进行这一表述，可能会比尝试捕捉行星大气层反射的恒星星光效果更好。

Based on the radiation transmission theory, a model of optical backscatter and signal of atmosphere range-gated imaging system is given.

以辐射传输理论为基础，建立了大气距离选通成像系统后向散射光和信号光的模型。

The image transmission wasn't perfect and suffered defects because the Earth's atmosphere caused errors, even when the sky was clear, NASA said.
