An ultrafast 3D camera developed in the lab of Lihong Wang at Caltech is capable of capturing the movement of light in three dimensions. The camera records in stereo at 100 billion frames per second. The research builds upon previous endeavors by Wang to develop compressed ultrafast photography (CUP) cameras, and relies on the same underlying technology. In CUP, all frames of the video are captured in one action without repeating the event. In this instance, Wang added stereoscopic functionality to the device to allow it to see in 3D. However, he didn’t do this by adding a second...Read full articleRelated content from Photonics MediaARTICLESCamera Offers Single-Shot, Real-Time, Ultrafast Imaging of Transparent ObjectsA camera developed at the California Institute of Technology (Caltech) uses picosecond imaging technology to take photographs and videos of transparent objects at speeds of up to 1 trillion frames...Photonics.com 1/23/2020New Lens Could Provide Thermal Imaging Capabilities in More Compact CameraUniversity of Utah researchers have developed a new kind of flat optical lens that is much thinner and lighter than conventional camera lenses.

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.
