摘　　要：文章介绍了实现超模式采样焦平面3种解决方案面临的技术难点,为避开器件问题提出了一 种新的斜模式采样方法。以任意两雏周期采样理论为基础分析了斜模式采样技术的物理原理,并通过实验 手段验证了斜模式采样技术的可行性。试验结果表明:改变探测器推扫方向的采样间距,斜模式采样技术 可以提高传输型光学遥感器图像的空间分辨率,该技术相对于超模式采样技术,工程实现上要简单。The technology difficulties of three solutions for supermode FPA is presented in the paper. In order to avoid these FPA difficulties, a new method called tilting mode sampling for EO sensor is invented. The principle of the method is analyzed on the base of two dimensional sampling theory. The flexibility of tilting mode sampling is validated through some experiments. The results show this sampling technology can improve the image spatial resolution of EO sensor through changing sampling distance in the direction of along push scan and the engineering implementation is relative simpler than that of supermode sampling.
