Abstract
The 2D optical decoded-image correlation is presented by using simultaneous compression of input image and the phase in the recording plane. The compressed input is encrypted via double random phase encoding. In recording plane, complex-valued wavefront is extracted, and only phase part is retained and compressed as ciphertext. During the decoding, due to the designed strategy, the decoded image cannot visually render information related to input image. The decoded-image correlation is conducted to verify whether the receiver possesses correct keys or is an authorized person. The method using simultaneous compression of input image and the phase in the recording plane could be used as a complementary alternative for optical information correlation.
