Researchers at Princeton University and the University of Washington (UW) designed a nanosize camera, no bigger than a grain of salt, that produces images comparable to those produced by a traditional lens setup more than 500,000 times larger than the nanosize device. To build a high-quality, ultracompact imager, the researchers devised a machine learning approach that allows the imager to learn a metasurface physical structure along with a neural feature-based image reconstruction algorithm. The researchers used neural nano-optics for end-to-end learning. They found that,...Read full articleRelated content from Photonics MediaARTICLESIntegrated Metaform Device Delivers Compact AR/VR EyewearA team from the University of Rochester’s Institute of Optics imprinted freeform optics with a metasurface, in a combination of optical technologies that charts a course for a new fabrication...Photonics Spectra July 2021 Issue2D Microlaser Arrays Enhance Stability, PowerResearchers from the University of Pennsylvania and Duke University designed and built 2D arrays of closely packed microlasers that demonstrated the stability of a single microlaser, and that...Photonics Spectra July 2021 IssueDevices Made of Multiple Materials Can Fit on a Single ChipA team of researchers at the University of Strathclyde has developed a highly accurate way to assemble multiple micron-scale optical devices extremely close together on a single chip.

Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookDigital Still Cameras: The Changing Face of Imaging: The digital camera reflects a sea change in the compact camera market.
