Polarization-multiplexing ghost imaging

Abstract

A novel technique for polarization-multiplexing ghost imaging is proposed to simultaneously obtain multiple polarimetric information by a single detector. Here, 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. Next, clear images of the different polarimetric information are recovered by demultiplexing the fused image. The application of this method to the detection of two different polarized objects is presented, and the results clearly demonstrate that the proposed method is effective. An encryption experiment for polarimetric information is also performed by setting the multiplexed speckles' encoding as the keys.
