论文摘要
幽灵成像是一种非凡的技术，它使用摄像机检测到永不与对象相互作用的光，并且仍然记录对象的图像。该方法依赖于使用相关光和附加的桶检测器。幽灵成像已用于考古学，生物医学氨酸，通过浑浊的媒体观看，并承诺改进X射线成像，以及许多其他应用。但是，幽灵成像比常规成像的优势很难量化。对于单个像素孔径（对象）的经典幽灵成像，我们使用基本统计信息找到了信噪比的封闭分析表达式。我们发现，当检测器充分嘈杂时，这种信号噪声比可以超过常规成像，而光圈相同的孔径暴露，这说明了简单且可量化的优势。数值模拟证实了理论分析。
Ghost imaging is a remarkable technique where light that never interacts with an object is detected with a camera and still the image of the object is recorded. The method relies on the use of correlated light and an additional bucket detector. Ghost imaging has been used in archaeology, bio-medicine, for seeing through turbid media, and promises X-ray imaging improvements, amongst many other applications. However, the advantage of ghost imaging over regular imaging can be difficult to quantify. For classical ghost imaging of a single pixel aperture (the object), we find a closed analytic expression for the signal-to-noise ratio using basic statistics. We find that this signal-to-noise ratio can exceed that of regular imaging with the same exposure of the aperture when the detectors are sufficiently noisy, illustrating a simple and quantifiable advantage. Numerical simulation confirms the theoretical analysis.
