By using deep learning to optimize the structures of a series of passive, isotropic diffractive layers, the team created a compact and broadband optical system that efficiently focuses light in ...

This book presents a comprehensive tutorial on propagation, diffraction and scattering problems from the basic principles of physical optics. Beginning with the fundamental differential and integral ...

Some of the mentioned applications require optics able to precisely manipulate laser beams in complex ways, often within a compact system. Beam splitter DOEs split a single incident laser beam into an ...

The optical diffraction is a major means of minute diameter measurements. Since the light intensity of the diffraction fringe, mainly distributed in the central bright stripes, and that will lead to a ...

In order to detect the spectral information of dynamic targets, different kinds of snapshot spectral imaging technologies have been proposed. Among them, the diffractive optical element based snapshot ...

Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have ...

Today's super-resolution microscopes have made it possible to observe the nanoscale world with unprecedented detail. However, they require fluorescent tags, which reveal structural details but provide ...

Spectrometer Gratings Ruled In Parallel on Multiple Substrates by Inprentus Inprentus, maker of ground-breaking custom blazed ...
