Description
In addition to direct and intensity interferometry techniques, heterodyning offers several unique advantages for stellar interferometry, and benefits from mature post-processing methods developed for radio astronomy. We introduce a new lab setup which explores potential improvements to stellar interferometry using NIR heterodyning. Constructed at the Max Planck Institute for Physics (MPP), the setup consists of entirely off-the-shelf components at 1.55 micron, a commercial SDR receiver, and a custom GNURadio data processing chain with minimal dead-time. We provide a description of the setup together with preliminary results and future plans.
