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 MediaARTICLESIngenuity Flight Rendered in 3DNASA engineers have rendered the the Mars helicopter Ingenuity’s third flight in three dimensions.

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 HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.
