Securing holographic three-dimensional information by digital fresnel field encryption
, J. Joseph, K. Singh
Published in Optical Society of America (OSA)
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. © 2006 Optical Society of America.
