Introduction
Optical image encryption is based on 2D Fourier Transform. A lense is able to get Bidimensional Fourier Transform of an Imagen in the focal plane. Many works in the state of art suggest to make analog image encryption/decryption by using lenses architectures.
Details
You are able to:
- Generate and Load from PC diferents Key for Encryption (Random Image Phase Distribution).
- Encrypt real images (png), and Decrypt Complex Images (mat).
- Visualize Complex Image generated for example through encryption.
Figure 1 shows final implmentation of the software tool.
