【摘要】：单像素成像技术具有利用一个单像素探测器获取高分辨图像的能力,近十年来得到广泛关注。该技术已应用于多个领域,如核磁共振成像、航天遥感、太赫兹成像和高光谱成像。与传统相机相比,单像素相机可以实现图像压缩和超宽的频谱工作范围。然而,单像素相机的成像速度受到数字微镜阵列和图像压缩程度限制,导致其时间分辨率较低(毫秒量级)。因此,观察显微成像中的高速动态现象对于单像素相机而言是巨大挑战。最近,基于光子时间拉伸的高速单像素成像技术被提出,其远超普通相机的成像速度也得到验证。本文介绍了光子时间拉伸技术的原理和应用,给出了高速单像素相机的结构,并通过实验证实利用该相机可实现高速和高吞吐量细胞流式分析,最后,讨论了高速单像素相机的局限和应用潜力。
[Abstract]:Single pixel imaging technology has been paid more and more attention in recent ten years because of its ability to obtain high resolution image using a single pixel detector. This technique has been applied in many fields, such as nuclear magnetic resonance imaging, space remote sensing, terahertz imaging and hyperspectral imaging. Compared with traditional camera, single pixel camera can achieve image compression and ultra wide spectrum range. However, the imaging speed of a single pixel camera is limited by the digital micromirror array and image compression, resulting in low temporal resolution (millisecond order of magnitude). Therefore, observing high-speed dynamic phenomena in microscopic imaging is a great challenge for single-pixel camera. Recently, a high speed single pixel imaging technique based on photon time stretching has been proposed, which is far faster than that of ordinary cameras. In this paper, the principle and application of photon time stretching technology are introduced, the structure of high speed single pixel camera is given, and it is proved by experiment that the high speed and high throughput cell flow analysis can be realized by using this camera. Finally, The limitation and application potential of high speed single pixel camera are discussed.
