2Pi Optics, Cambridge, MA, has introduced a high-resolution fisheye sensor based on optical metalens technology. This technology can be used by design engineers to further miniaturize the cameras used in advanced driver-assistance systems (ADAS), AR/VR, UAVs, robotics, and other industrial applications. 2Pi’s innovation addresses a crucial disadvantage of today’s miniature cameras: their complex and expensive optical lenses. This flat fisheye lens produces crisp, 180-degree panoramic images. The new lens is a replacement for conventional wide-FOV lenses, which are typically composed of multiple stacked lens pieces, with a single, thin, flat metalens. This approach enables the design of ultra-compact, high-performance optical imagers and sensors.
