Feasibility of a non-redundant pupil mask for in-flight wavelength measurements

Paper Abstract

The study of sparse aperture masking as a mean to extract spectral information is a relatively little investigated content. However, despite the loss of throughput that comes with this technique, it allows one to benefit from the many advantages brought by interferometry, without the need of complex phase-controlled systems.
In this paper, we analyse the potential of non-redundant aperture masking for spectral measurements, highlighting its capabilities both as a tool for precise single-wavelength metrology, and as alternative to low resolution spectrographs.
Although here presented as a general introduction, this technique is suitable for a large number of potential applications, ranging from compact cube-sat missions for the analysis of bright sources, to large-dish space telescopes where the increased sensitivity allows one to study fainter targets.
