Accurate high magnification of small aperture laser beams has traditionally been a challenge because the optics associated with such a beam expander are difficult to test using an optical ...

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 ...

This 22x stabilized binocular from Kite is built for birders who want more reach ...
