抽象。我们提出了一种几何传感器来恢复局部倾斜的分割表面使用的货车大坝和车道算法[M。A.货车达姆河G. Lane,Appl.Opt.41(26),5497-5502(2002)]。本文还提出了一种实现该算法使用图形处理单元作为专用硬件。这种计算统一设备架构实现在大气稳定时间内实现了高达1024×1024像素分辨率的实时结果。
Abstract. We present a geometric sensor to restore the local tip-tilt in a segmented surface using the Van Dam and Lane algorithm [M. A. van Dam and R. G. Lane, Appl. Opt. 41(26), 5497–5502 (2002)]. The paper also presents an implementation of this algorithm using graphical processing units as specialized hardware. This compute unified device architecture implementation achieves real-time results inside the stability time of the atmosphere for resolutions of up to 1024×1024 pixels.
