【摘要】：單像素成像技術(shù)具有利用一個單像素探測器獲取高分辨圖像的能力,近十年來得到廣泛關(guān)注。該技術(shù)已應用于多個領域,如核磁共振成像、航天遙感、太赫茲成像和高光譜成像。與傳統(tǒng)相機相比,單像素相機可以實現(xiàn)圖像壓縮和超寬的頻譜工作范圍。然而,單像素相機的成像速度受到數(shù)字微鏡陣列和圖像壓縮程度限制,導致其時間分辨率較低(毫秒量級)。因此,觀察顯微成像中的高速動態(tài)現(xiàn)象對于單像素相機而言是巨大挑戰(zhàn)。最近,基于光子時間拉伸的高速單像素成像技術(shù)被提出,其遠超普通相機的成像速度也得到驗證。本文介紹了光子時間拉伸技術(shù)的原理和應用,給出了高速單像素相機的結(jié)構(gòu),并通過實驗證實利用該相機可實現(xiàn)高速和高吞吐量細胞流式分析,最后,討論了高速單像素相機的局限和應用潛力。
[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.
