Abstra We develop a novel kind of single-pixel imaging (SPI) scheme to reconstruct high-quality images of the axially fast-moving target by utilizing the non-diffracting beam illumination. In this paper, a kind of cosine shaped source is elaborately designed and introduced for the first time in the SPI scheme to realize the reconstruction of the dynamic target. The imaging formula for the SPI system with the cosine shaped source is theoretically derived and numerical examples are given to see clearly the influences of system parameters and motion models of the target on the image quality. Our results show that the image quality and imaging efficiency of the SPI system for the static or dynamic target can be significantly improved by utilizing the cosine shaped source, due to its non-diffracting and orthogonal features. Even there exists strong scattering media, our SPI proposal can still work well for the static or dynamic target. Therefore, our work offers great promise for the SPI real application in forward-looking lidar detection.

通过非衍射光束对动态目标进行单像素成像

Abstra 我们开发了一种新型的单像素成像 (SPI) 方案，通过利用非衍射光束照明重建轴向快速移动目标的高质量图像。本文首次在SPI方案中精心设计并引入了一种余弦形源，实现了动态目标的重构。从理论上推导出余弦形源SPI系统的成像公式，并给出数值算例，以清楚地看出系统参数和目标运动模型对成像质量的影响。我们的结果表明，利用余弦形光源，由于其非衍射和正交特性，可以显着提高 SPI 系统对静态或动态目标的图像质量和成像效率。即使存在强散射介质，我们的 SPI 建议仍然可以很好地处理静态或动态目标。因此，我们的工作为 SPI 在前瞻性激光雷达检测中的实际应用提供了广阔的前景。
