Far-field Imaging beyond the Diffraction Limit Using a Single Radar
Lianlin Li, Fang Li, Tiejun Cui +2
Far-field imaging beyond the diffraction limit is a long sought-after goal in various imaging applications, which requires usually an array of antennas or mechanical scanning. Here…
Theory of the far-field imaging beyond the Rayleigh limit based on the super-resonant lens
Lianlin Li, Fang Li, Tiejun Cui
Essentially, the idea of improving the resolution of a given imaging system is to enhance its information capacity represented usually by the temporal-bandwidth (or, spatial-spectr…
Far-field subwavelength imaging from a single broadband antenna in combined with strongly disordered medium
Lianlin Li, Fang Li, Tie Jun Cui
The far-field subwavlength imaging is a challenging issue. In this letter we demonstrate numerically that the far-field subwavelength imaging of weakly scattering objects can be ob…
Subwavelength imaging of sparse broadband sources surrounded by an open disordered medium from a single antenna
Lianlin Li, Fang Li, Tie Jun Cui
In this letter we study the subwavelength imaging of sparse broadband sources inside a disordered medium by processing the data acquired by a single antenna. A mathematical model h…
Beat the Rayleigh limit: OAM based super-resolution diffraction tomography
Lianlin Li, Fang Li
This letter is the first to report that a super-resolution imaging beyond the Rayleigh limit can be achieved by using classical diffraction tomography (DT) extended with orbital an…
