We propose a holographic display system involving face recognition, air-writing, and multiple point cloud gridding encryption (M-PCGE) methods to provide multi-level security for objects. The feasibility of the propos...

A method using multi-level derivative spectral fusion is proposed to improve the resolution for off-axis digital holographic imaging. Some experiments are performed to verify the feasibility and validity of the propos...
