Optical Encryption.

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.
