Securing Holographic Three-dimensional Information by Digital Fresnel Field Encryption

Not Accessible

Your library or personal account may give you access

Abstract

Complex Fresnel field retrieved from a digital off-axis Fresnel hologram is encrypted. Object information is directly decrypted in a single step. The noisy nature of the Fresnel field is helpful for single random phase encoding.
