单像素成像，也被称为计算幽灵成像，提供了一种替代方法来执行成像的各种应用，如多波长成像，三维成像，以及通过湍流成像，这对于具有像素化探测器的传统相机来说是困难的。近年来，许多改进已经成功地提高了单像素成像系统的信噪比，显示了该技术在工程上的可行性。然而，许多这些改进都是基于实证研究结果。在这项工作中，我们对影响基于焦平面调制的单像素成像系统中重建图像质量的每个系统组件的噪声进行了调查。建立了一个集体噪声模型来描述这些不同噪声源的综合影响，并进行了数值模拟来量化这种影响。通过实验对模型进行了验证，结果与仿真结果吻合较好。这项工作提供了一种简单而准确的方法来评估单像素成像系统的性能，而无需进行实际的实验测试。
Single-pixel imaging, also known as computational ghost imaging, provides an alternative method to perform imaging in various applications which are difficult for conventional cameras with pixelated detectors, such as multi-wavelength imaging, three-dimensional imaging, and imaging through turbulence. In recent years, many improvements have successfully increased the signal-to-noise ratio of single-pixel imaging systems, showing promise for the engineering feasibility of this technique. However, many of these improvements are based on empirical findings. In this work we perform an investigation of the noise from each system component that affects the quality of the reconstructed image in a single-pixel imaging system based on focal plane modulation. A collective noise model is built to describe the resultant influence of these different noise sources, and numerical simulations are performed to quantify the effect. Experiments have been conducted to verify the model, and the results agree well with the simulations. This work provides a simple yet accurate method for evaluating the performance of a single-pixel imaging system, without having to carry out actual experimental tests.
