This study proposes a new multi-image asymmetric polarization optical encryption method based on the full-vector light field control and Fourier transform frequency shifting. First, multiple images to be encrypted are coherently superimposed to form a complex amplitude optical image after the random phase modulation, Fourier transforms, and frequency shifting phase modulation. Next, the distribution of the image is the interference of two pure phase masks, and is encoded and loaded into the full-vector light field control system based on the 4F system. Finally, the all-optical control vector light field outputs amplitude type encrypted images and keys after passing through the polarizer, which are received by CCD to realize parallel encryption of multiple images. Multiple decrypted images can be obtained during decryption by solving the relationship between the control light field distribution (full vector distribution) and the encrypted image under the condition of the correct key. Any rotation angle of the polarizer and the phase only image obtained by interference decomposition are used as the key, which greatly improves the security of the optical image encryption system. The encryption of multiple images into a single amplitude-type encrypted image is convenient for storage and transmission, which improves encryption efficiency. A simulation study has verified the effectiveness and feasibility of the proposed multi-image encryption scheme, and the experimental results show that the proposed method has high security, noise resistance, shear resistance, and chosen-plaintext attack resistance, which has specific application prospects.
