Researchers have designed a new compact camera that acquires wide-angle images of high-quality using an array of metalenses—flat nanopatterned surfaces used to manipulate light. By eliminating the ...

Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...

Let’s make a New Year’s resolution, phone companies. We can do it together. You will stop putting disappointing and/or useless cameras on the back of your phones, and I will stop complaining about ...

Researchers have designed a new, ultrathin camera that acquires wide-angle, high-quality images using a metalens array. This approach eliminates bulky and heavy lenses, possibly enabling the ...
