摘要
本文主要论述多片面阵CCD图像传感器焦平面光学拼接原理、结构设计及拼接精度,并给出了一个四片成2×2方阵的面阵CCD拼接样机结果。总像元数达1.42×10~6个,搭接精度1.5μm,共面精度5μm。拼接可大幅度地提高光电接收器的总像元数,并在实际工程中应用。
The focal plane assembly principle, construction and assembly accur-acy of multiple area CCDs are described in the paper, and the assembly resultsfor a 2×2 array of area CCD are given. Its total pixel numbers are1.42×10~6, assembly accuracy is less than 1.5μm. Common plane accuracy is5μm. The assembly can raise total pixel numbers of photodetector in largescale, and can be applied to practical engineering.
