    Binary star astrometry with milli and sub-milli arcsecond precision by Jankov S., Cvetković Z., Pavlović R.

    Published 2014-01-01
    “…In this paper we review the representative results of techniques which have already allowed the sub-milli arcsecond precision like the optical long baseline interferometry, as well as the precursor techniques such as speckle interferometry, adaptive optics and aperture masking. These techniques provide a step forward from milli to sub-milli arcsecond precision, allowing even short period binaries to be resolved, and often resulting in orbits allowing precisions in stellar dynamical masses better than 1%. …”

    Microscope-Cockpit: Python-based bespoke microscopy for bio-medical science by Phillips, MA, Susano Pinto, DM, Hall, N, Mateos-Langerak, J, Parton, RM, Titlow, J, Stoychev, DV, Parks, T, Susano Pinto, T, Sedat, JW, Booth, MJ, Davis, I, Dobbie, IM

    Published 2021
    “…We demonstrate the advantages of the Cockpit platform using several bespoke microscopes, including a simple widefield system and a complex system with adaptive optics and structured illumination. A key strength of Cockpit is its use of Python, which means that any microscope built with Cockpit is ready for future customisation by simply adding new libraries, for example machine learning algorithms to enable automated microscopy decision making while imaging.…”
