Image scanning microscopy based on multifocal metalens for sub-diffraction-limited imaging of brain organoids [PDF]

open access: yesLight: Science & Applications
Image scanning microscopy (ISM) is a promising imaging technique that offers sub-diffraction-limited resolution and optical sectioning. Theoretically, ISM can improve the optical resolution by a factor of two through pixel reassignment and deconvolution.

Multifocal metalens for detecting several topological charges at different wavelengths [PDF]

open access: yesКомпьютерная оптика, 2023
A combined high-aperture metalens in a thin silicon nitride film, which consists of two inclined sector metalens, is considered. Each sector metalens consists of a set of binary subwavelength gratings. The diameter of the lens is 14 μm. It has been shown

Enhanced optical performance of multifocal metalens with conic shapes. [PDF]

open access: yesLight Sci Appl, 2017
A multifocal metalens, which focuses incident light at multiple foci, has many applications in imaging systems and optical communications. However, the traditional design strategy of a multifocal metalens combines several lenses that have different focal points into a planar integrated unit, resulting in low imaging quality because of the high ...
