单像素成像在特殊波段及三维成像的应用发展

与传统的面阵成像技术不同,单像素成像技术作为一种新型的计算成像技术,使用不具备空间分辨能力的桶探测器,结合空间光场调制技术,通过关联算法重构待成像物体的空间强度信息,在研究界得到了广泛的关注。近年来,单像素成像技术被广泛应用于各种波段的成像领域,尤其是在某些面阵探测器价格昂贵甚至无法制备的特殊波段,单像素成像技术逐步发展为一项低成本高成像质量的替代技术。并且,在三维成像技术中,大量基于单像素成像的相关研究工作也被相继提出。文中主要介绍了单像素成像技术的基本原理及应用发展历程,并着重介绍了其在条纹结构投影三维成像技术中的应用工作。

Application and development of single pixel imaging in the special wavebands and 3D imaging

Different from traditional array-detector imaging technology, single pixel imaging(SPI) technology, which is considered as a novel computational imaging technology, uses a bucket detector with no spatial resolution capability and combines with the spatial light field modulation technology to reconstruct the intensity of the object by correlation algorithm, which has received extensive attention. In recent years, SPI has been widely used with different light source, especially in some special wavebands, where the array-detectors are expensive or even impossible to be made. SPI has gradually developed into an alternative technology with low cost and high quality. In addition, a large number of works of SPI have been proposed in 3D imaging technology. The basic principle and application development of single pixel imaging was introduced. Its application in fringe projection 3D imaging was also introduced emphatically.
