Paper Abstract

This paper reports results on scrambling gains with fibres and light pipes for linking telescopes to spectrographs aiming high accuracy measurements on radial velocities. The use of the so-called homogenizers is proposed as an alternative or in addition to increase the scrambling gain in optical and mechanical scramblers. The results on a light pipe to homogenize the flux of 4 fibres arranged on a line in order to get a uniform slit aperture is also reported
