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
