航天TDICCD相机静态调制传递函数的研究

Research of the Static MTF for the Aerospace TDICCD Camera

文章从分析国内外航天TDICCD相机出发 ,研究得出 ,在实验室测得相机奈奎斯特频率 (fN)处的静态调制传递函数 (MTF)达到 0 .1 5 ,则相机星载时 ,就可达到fN 对应的地面像元分辨率 ,即设计要求的分辨率。

From the research of the aerospace TDICCD cameras of China and overseas,it has been found that,if the static MTF at Nyquist frequency( f N ) is up to 0.15 in laboratory, the ground pixel resolution responding to the f N ,i.e., the desired resoluton will be met onboard.
