abstract = "In this paper, we propose an optical method based on integral imaging(II) and ptychography to encrypt threedimensional( 3D) information with simple architecture. The 3D scene plaintext is encrypted by a camera array and double-random phase masks via ptychography to generate a series of diffraction intensity patterns as ciphertexts. Then, the decrypting process with ptychographic iteration and II reconstruction is employed to retrieve high-quality 3D images. Since scanning light probes and parameters of II can serve as secret keys that enlarge the key space, and elemental image array generated by the II pickup has redundancy property, the security of encryption scheme can be improved significantly. Also, the decrypted 3D images in our proposed method have high-quality. Preliminary experiments are carried out, and the results demonstrate the feasibility and robustness of our proposed method. Especially, this research is suitable for real large-size 3D scene.",
