摘要：

We present an algorithm for reconstructing an object complex field with resolution below that of an image sensor (subpixel resolution) in single-shot diffractive imaging with coded diffraction. The algorithm employs subpixel phase retrieval and sparse regularization based on compressive sensing. This is useful for high-speed or high-sensitivity imaging using an image sensor with a low pixel count and/or a large pixel size. We experimentally demonstrated the proposed method with two types of moving objects. (C) 2017 Optical Society of America
