Abstract
In the context of space-based optics, contamina-tion due to particle deposition on the optics is inevitableand constitutes a critical issue. This gets more challengingfor the sensitive heterodyne measurements of the Laser In-terferometer Space Antenna (LISA), the space-based grav-itational wave observatory to be launched in 2034. There-fore, table-top experiments need to be developed for a bet-ter understanding of how micrometer to millimeter sizeddust particles, present on optical surfaces, affect LISA mea-surements. In this work, we present an experimental set-up for the simultaneous measurement of the coherentbackscattering and the monitoring of particles depositionon the optics to be tested. The results of the first measure-ments are presented and discussed in this article.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
