CONCEPT FOR FIBER-BASED NEAR-INFRARED INTERFEROMETRY OF HIGHEST FREQUENCY RESOLUTION

Michael EA; Besser, F; Prado R.; Pallanca L.

Abstract

We are presenting first experimental results for subsystems of a low-cost near-infrared heterodyne interferometer concept based on commercial 1.55 mu m fiber-components with relative phase-stabilization between both telescopes, a shot noise limited heterodyne scheme with ambient temperature operated photodiodes, an ultra-coherent fiber laser, and a ROACH-based correlator. After we worked on a first demonstration with two 14 amateur telescopes on Betelgeuse, the concept should be upgradable to connect mid- or large-class telescopes, also given that the employed fiber phase stabilization scheme will enable the operation of long baselines.
