Advances on techniques of breaking diffraction limitation using scattering medium
摘要
Abstract
This paper provides the state-of-art review to the research works in diffraction-limit breaking focu-sing and imaging .Firstly, the research background and significance of the research in this field are given , and the well-developed super-resolution methods and the definition of scattering media towards diffraction -limit breaking imaging are also introduced .Secondly , the time reversal technique utilizing the scattering property in acoustics and electromagnetics for signal compressing and focusing are specified .The realization method of time reversal in domain of optics is presented .As a foundation for better understanding , the advantages brought about by inserting a plate of scattering media into certain optical imaging system are further elabora-ted.Thirdly, this review analyzes the serial feedback controlling method , optical phase conjugation and the transmission measurement based on phase conjugation for finest focusing .The groundbreaking transmission matrix measurement in both spatial and spatial frequent domain is introduced , which is followed by the prepa-ration of scattering media aiming at the far-field and wide-field diffraction-limit breaking imaging using trans-mission matrix method .Finally, the advances and prospect on techniques of breaking diffraction limication u-sing scattering medium are preposed .关键词
