Performance comparison of computational ghost imaging versus single-pixel camera in light disturbance environment

Single-pixel computational ghost imaging with helicity-dependent metasurface hologram

Different optical imaging techniques are based on different characteristics of light. By controlling the abrupt phase discontinuities with different polarized incident light, a metasurface can host a phase-only and helicity-dependent hologram. In contrast, ghost imaging (GI) is an indirect imaging modality to retrieve the object information from the correlation of the light intensity fluctuatio...

Imaging around corners with single-pixel detector by computational ghost imaging

Bin Bai, Jianbin Liu, Yu Zhou, Songlin Zhang, Yuchen He, and Zhuo Xu Abstract We have designed a single-pixel camera with imaging around corners based on computational ghost imaging. It can obtain the image of an object when the camera cannot look at the object directly. Our imaging system explores the fact that a bucket detector in a ghost imaging setup has no spatial resolution capability. A ...

Single-pixel digital “ghost” holography

3D computational imaging with single-pixel detectors.

Computational imaging enables retrieval of the spatial information of an object with the use of single-pixel detectors. By projecting a series of known random patterns and measuring the backscattered intensity, it is possible to reconstruct a two-dimensional (2D) image. We used several single-pixel detectors in different locations to capture the 3D form of an object. From each detector we deriv...

EPR-based ghost imaging using a single-photon- sensitive camera

Correlated photon imaging, popularly known as ghost imaging, is a technique whereby an image is formed from light that has never interacted with the object. In ghost imaging experiments, two correlated light fields are produced. One of these fields illuminates the object, and the other field is measured by a spatially resolving detector. In the quantum regime, these correlated light fields are ...
