Definition
Relating to the horizontal direction or angle of a celestial object or an optical field, specifically referring here to the angular orientation of the Hilbert transform used to process light.
Etymology
The word comes from the Arabic 'as-sumūt', meaning 'the directions' (the plural of 'samt', meaning 'direction' or 'path'). It entered English via medieval Latin and Old French.
In the news
The article describes using 'azimuthal' Hilbert transform metasurfaces to process light in an angular direction, which allows the system to identify corners in images more efficiently.
