Abstract

High contrast imaging techniques such as aperture masking interferometry allow for the detection of faint companions such as substellar companions by utilizing light from the planet itself. This allows access to study a larger population of planetary companions as compared to the transit technique where only systems viewed edge on can be studied, for example. However, aperture masking has several shortcomings including, low throughputs, limited Fourier coverage, and leakage of residual atmospheric noise due to phase corrugations across each sub-apertures. These limitations can be overcome by remapping the pupil with single-mode waveguides. We present an integrated pupil remapping interferometer, known as Dragonfly, that aims to do just that. We discuss the progress we have made over the past year in developing a stable and robust instrument and elucidate challenges and the innovative solutions that were applied. Finally we discuss improvements to the instrument that will enable future scientific endeavors and outline the expected performance limitations.
