The experimental system.

The whole system is sketched in Fig. 4.1. It consists in the light source, the sample cell and the image forming, capturing and processing system. In the first sections we describe all these parts and the criteria we followed to build our NFS instruments. In Sections 4.7 and 4.8 we describe the three NFS instruments we built.
