压缩传感已被用于提高传感器阵列的分辨率，允许从低分辨率甚至单像素传感器获得高分辨率图像。本文介绍了一种用于压缩成像的旋转编码孔径，它具有其他传感策略所不具备的优势。编码几何结构的设计受到成像器旋转的限制。通过最小化感测矩阵的互相干来优化块-解块码型。给出了仿真结果，使用最终的代码设计成功地从非常小的传感器阵列恢复了高分辨率图像。
Compressive sensing has been used to increase the resolution of sensor arrays, allowing high-resolution images to be obtained from low-resolution or even single pixel sensors. This paper introduces a rotating coded aperture for compressive imaging that has advantages over other sensing strategies. The design of the code geometry is motivated by constraints imposed by the imager's rotation. The block-unblock code pattern is optimized by minimizing the mutual coherence of the sensing matrix. Simulation results are presented, using the final code design to successfully recover high-resolution images from a very small sensor array.
