Speckle free optical watermarking based on pseudo-random phase encoding
Watermarking is a process of embedding copiright information into an image to verify the ownership without any kind of corruption. In optical applications, the usage of diffusers is required to obtain a homogeneously distributed spectrum. However, the use of a diffuser in the input plane and the fin...
