TL;DR: Simulation results show that the proposed phase retrieval process has high convergence speed, and the encryption algorithm can avoid cross-talk; in addition, its encrypted capacity is considerably enhanced.

TL;DR: An optical approach of silhouette-free multiple-image encryption based on interference is proposed, with two layers to enhance the level of security, by considering the fractional order as an additional key.

TL;DR: A novel multiple-image encryption scheme using the nonlinear iterative phase retrieval algorithm in the gyrator transform domain under the illumination of an optical vortex beam to improve the security level of the cryptosystem and increase the randomness is proposed.

TL;DR: The annoying silhouette problem existed in the interference-based encryption methods can be avoided effectively and a set of numerical simulations are presented to demonstrate the validity and feasibility of the proposed technique.

TL;DR: The reported approach provides an effective alternative for enriching the related research on single-pixel correlated imaging systems and reduces the number of recording the measured intensities in the process of imaging, which results in high efficiency.
