An all optical JPEG compression for colored images

The optical images compression was the subject of several research in the last decade because the coherent light, with its speed and the property to carry out a two-dimensional Fourier transformation instantaneously with coherent optics on the one hand (thanks to a convergent lens) and new technologies on the electro-optical interfaces on the other hand (modulating space of light SLM), makes it possible to quickly compress generally colored images. It gives us a real asset because the compression time is decreased and the field of the images to be compressed is increased. In this article we present an all optical method of colored images compression based on JPEG standard. This architecture will be validated by simulation and an optical setup of implementation will be proposed.
