文摘
- •
An optical security system is proposed based on inference principle and phase retrieval with sparsity constraints.
- •
The primary image can only be reconstructed after the two POMs are authenticated, which improves the security levels.
- •
It allows users to authenticate the two POMs without visual observation of those images used as references.
- •
No holographic scheme is involved in the proposed optical verification and encryption system.
