Resumen:
Theta modulating techniques are now applied for multiplexing encrypted images in order to avoid cross-talk and background noise in the decoded data. The use of phase gratings instead of amplitude gratings introduce an energy distribution leading to a final contrast improvement in the decrypted images.
