Optical Cryptography-Based Temporal Ghost Imaging With Chaotic Laser

In this letter, compressive temporal ghost imaging with chaotic laser is applied to optical encryption with good time-controllable random characteristics and a second-order time correlation property. The security, feasibility, and applicability of our method are verified on the basis of the research on the encryption mechanism. The experiment suggests the method can obtain high-quality recovery signal, resist noise attack, and apply to different kinds of signals. This technique can be immediately applied to encryption and telecommunication with the advantages of high security, wide applicability, and high quality of reconstructed information.
