Snapshot Compressive Imaging by Phase Modulation

随着对成像分辨率的要求日益提高,成像所需采集的数据量不断增大,亟需发展一种具有更高图像信息获取效率的压缩成像方式。压缩感知信息理论的兴起使压缩成像研究得到了快速的发展。提出了一种基于空间随机相位调制的单次曝光压缩感知成像方案,通过压缩成像实验验证了该成像方案在原理上的可行性。理论分析并实验验证了系统的空间分辨能力、信噪比随系统参数变化的相互制约关系。

With the increasing need for higher image resolution and amount of data for imaging, it is imperative to develop novel compressive imaging technology with higher information acquiring efficiency. The rise of compressive sensing theory paves the way for compressive imaging. A snapshot compressive imaging strategy by spatial phase modulation is proposed. The feasibility for the imaging strategy is testified by compressive imaging experiment. The spatial resolution and signal noise ratio are analyzed by theory and testified by the experiments, the restrictive relation between them is released.
