摘　　要：用机载仪器获取地物的偏振信息需要同步得到三个偏振方向的图像数据。论文介绍了机载偏振CCD相机中数据采集与记录系统的结构,阐述了基于PCI总线的多路、高速数据采集卡的实现方案和工作原理,给出了用WinDriver编写windows2000环境下PCI数据采集卡驱动程序的实例方法与步骤。When using airborne device to get polarized information of the objects on the ground,we must get the image data of three polarized directions synchronically.This article introduces the structure of data acquisition and record sys-tem of the airborne polarized CCD cameras,then explains the implement scheme and working principle of the muti-PCI and high speed data acquisition cards,in the end gives the method and procedure of driver programming of the PCI data acquisition card using WinDriver under Windows2000circumstance.
