A British nanotech invention has revolutionized the humble optical microscope by quadrupling its magnification power to a level far beyond what could previously be achieved with visible light. The new ...

Diffractive deep neural networks (D 2 NNs) are optical systems composed of successive transmissive layers optimized through deep learning to perform computational tasks in an all-optical manner. The ...

A periscope camera lens is a lens assembly that uses prisms, mirrors, or a combination of them to redirect light before it reaches the camera sensor. In doing so, it magnifies the image more so than ...

Optical microscopy is a very useful technique to examine the appearance of a sample with greater detail, but there are some limitations that provide a boundary to its use in practice. Cross section of ...
