由于单台推扫式相机(或成像光谱仪)视场较窄，通常采用多个相机模块进行视场拼接。针对相机的图像数据具有分辨率高、数据量大特点，提出了一种基于CCSDS的高速复接的传输方法。高速复接电路采用FPGA产生各种控制信号，选用TI的SN65LV1023和SN65LV1224串化解串芯片，把模拟的相机数据转化为一对LVDS差分信号输出。在接收端，用ADLink公司的PCI7300采集卡采集数据进入电脑，用VC＋＋编写软件恢复图像数据。实验结果表明，高速复接电路能够高效可靠的传输图像数据并恢复数据时钟。

Owing to the narrow field of view of single pushbroom imaging spectrometers, one of a better way to enlarge total field of view is to combine multiple fields from several modules. The Images of camera usually has a huge amount of data with high-resolution, we advance a method to transport the image data. It is based on CCSDS protocol. The high speed interface electric circuits adopt FPGA to generate all kinds of controls parameter. We use serDes SN65LV1023 and SN65LV1224of TI to transform analog camera images data into a pair of LVDS. On the receiver, the camera images data is acquired by PCI7300 of ADLink. We use software to recover the camera images data on the computer. Since its high speed and stability and expandability, the High Speed Interface electric circuits can service as a reference model for such a multi-camera transport designs.
