New paper in Applied Optics about a new optical encryption technique
A new paper has been published in Applied Optics entitled New key based on tilted lenses for optical encryption, that describes a novel concept based on tilted spherical lenses for optical encryption using Lohmann’s type I systems. An experiment is presented, considering a hybrid encryption/decryption process where the image is numerically encrypted but optically decrypted.
This work was developed by our friends at the University of Valencia and we contributed by developing a experimental system that demonstrates the procedure.
