Different Channels to Transmit Information in a Scattering Medium
Xuyu Zhang, Jingjing Gao, Yu Gan +6
A channel should be built to transmit information from one place to another. Imaging is 2 or higher dimensional information communication. Conventionally, an imaging channel compri…
Roles of scattered and ballistic photons in imaging through scattering media: a deep learning-based study
Xuyu Zhan, Jingjing Gao, Yu Gan +6
Scattering of light in complex media scrambles optical wavefronts and breaks the principles of conventional imaging methods. For decades, researchers have endeavored to conquer the…
Speckle-based optical cryptosystem and its application for human face recognition via deep learning
Qi Zhao, Huanhao Li, Zhipeng Yu +7
Face recognition has recently become ubiquitous in many scenes for authentication or security purposes. Meanwhile, there are increasing concerns about the privacy of face images, w…
Scattering medium: randomly packed pinhole cameras
Honglin Liu, Xin Wang, Puxiang Lai +3
When light travels through scattering media, speckles (spatially random distribution of fluctuated intensities) are formed due to the interference of light travelling along differe…
Lensless Wiener-Khinchin telescope based on high-order spatial autocorrelation of thermal light
Zhentao Liu, Xia Shen, Honglin Liu +2
The resolution of a conventional imaging system based on first-order field correlation can be directly obtained from the optical transfer function. However, it is challenging to de…
Sub-wavelength Coherent Imaging of a Pure-Phase Object with Thermal Light
Minghui Zhang, Qing Wei, Xia Shen +4
We report, for the first time, the observation of sub-wavelength coherent image of a pure phase object with thermal light,which represents an accurate Fourier transform. We demonst…
Transmission area and two-photon correlated imaging
Yanfeng Bai, Shensheng Han, Honglin Liu
The relationship between transmission area of an object imaged and the visibility of its image is investigated in a lensless system. We show that the changes of the visibility are…
Fourier Analysis of Ghost Imaging
Honglin Liu, Jing Cheng, Yanfeng Bai +1
Fourier analysis of ghost imaging (FAGI) is proposed in this paper to analyze the properties of ghost imaging with thermal light sources. This new theory is compatible with the gen…
Lensless Fourier-Transform Ghost Imaging with Classical Incoherent Light
Minghui Zhang, Qing Wei, Xia Shen +4
The Fourier-Transform ghost imaging of both amplitude-only and pure-phase objects was experimentally observed with classical incoherent light at Fresnel distance by a new lensless…
