摘要

为了满足空间宽幅相机大视场的需求

研究了对多片CCD器件进行拼接以获得超长焦平面组件的方法。使用长线阵时间延迟积分(TDI)CCD拼接仪

按照设计位置和精度要求把17片TDICCD器件拼接到焦平面板上

用销钉定位

获得了长为600 mm、像元为69 000个的超长焦平面。然后

对完成拼接的焦平面组件进行了高低温循环试验、热真空试验和振动试验。实验结果表明

焦平面组件的结构设计和材料选取满足力学/热学要求。对完成拼接的600 mm长焦平面组件进行了TDICCD拼接精度的检测

检测结果显示拼接误差小于3 m。将该超长焦平面组件用于遥感相机

通过成像实验获得了清晰的无缝宽幅图像。上述结果证明600 mm长焦平面组件满足空间宽幅相机的应用需求。

Abstract

A method to assemble muti-chip CCD devices together for a long focal plane assembly was proposed to meet the need of a space wider format camera for large field of view. By using a long array Time Delay Integration CCD(TDICCD) mosaic apparatus

17 TDICCD devices were stitched onto the focal plan board with an interleaving assembly method according to the accuracy requirements

and fixed by plugs

then an extra long focal plane with a length of 600 mm

pixels of 69 000 was obtained. The experiments on the completed focal plane assembly were performed by a temperature cycling test

a vacuum thermal test and a vibration test

and the results show that structure design and material selection of the focal plan assembly meet the mechanical and thermal requirements. The accuracy measurment result of focal plane shows that the stitching error is less than 3 m. The extra long focal plane was applied to a remote sensing camera

and the seamless wider format image was captured. These results testify that the 600 mm long focal plane assembly meets the application needs of wide format remote sensing cameras.
