IF N,u,η are the refractive index, the paraxial angle, and the size of object respectively, and dashes denote these quantities in the image space, then the magnification formula, is valid for ...

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 ...

Professor Aydogan Ozcan and his research team at UCLA have created a pyramid-structured diffractive optical network that scales its layers pyramidally to match the direction of image magnification or ...

An exceptional component offered by Knight Optical – the leading supplier in high-quality, metrology-tested optics – is the Fresnel Lens; popular for a range of uses, from integration with traffic ...

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 ...
