Abstract
An information-encryption method based on computer-generated
hologram (CGH) interference is presented. In this method the
original information is decomposed into two parts, and then each part
is encoded on a separate CGH. When these two encoded CGHs are
aligned and illuminated, a combined interference pattern is
formed. The original information is obtained from this
pattern. It is impossible to decrypt the original information from
one CGH alone; two matched CGHs must be put together to make it
available.
