中文摘要: 近十年来,热光关联是量子成像领域中的研究热点之一。在非相干光场照明下,利用关联能够实现无透镜成像与傅里叶变换。因而热光关联在X射线成像、图像识别等领域中都具有潜在的应用前景。本项目将采用理论与实验相结合的研究方法,进一步揭露热光关联中的位相共轭效应,借助于压缩感知理论与挑选关联成像思想,探索缩短热光关联成像曝光时间的方法,采用无透镜傅里叶变换实现图像识别。通过对这些的研究可使我们加深对关联本质的认识,发现新的物理现象,提高关联成像的成像速度,为图像识别提供新的途径。

英文摘要: The correlation with thermal light is one of the hot research topics in the field of quantum imaging during the past decade. Under incoherent illumination, imaging and Fourier transform can be realized through correlation without lens, thus it has potential applications in many fields such as X-ray imaging and pattern recognition. This project will adopt theoretical-experimental method. These main investigating aspects will be focused on further uncovering the phase conjugation effect of correlation with thermal light, searching new way to shorten exposure time of correlation imaging with the help of compressive sensing and selective correlation imaging, and realizing pattern recognition by lenseless Fourier transform. Through the research, we could deepen our understanding of the nature of correlation, discover new physical phenomena, enhance the correlation imaging speed, provide a new way for pattern recognition.
