Polarization-multiplexing ghost imaging

•Existing research methods on polarimetric ghost imaging use multiple detectors or time-difference acquisition to obtain different polarimetric information and recover the object information. In contrast, in this paper, the spatial polarization multiplexing method is employed to acquire multiple polarimetric information simultaneously by only one single-pixel detector.•Polarization-division multiplexing speckles are employed for object illumination. The light reflected from the objects is detected by a single-pixel detector. An iterative reconstruction method is used to restore the fused image containing the different polarimetric information by summing the multiplexed speckles and detected intensities. Clear images of the different polarimetric information are recovered by demultiplexing the fused image.•The results of experiment have verified that our proposed method can be effective to recover the multiple polarimetric information.
