2Pi Optics has unveiled a brand new type of fisheye digicam based mostly on what it calls metasurface optics.
The corporate plans to indicate off the tech at CES 2024, the massive tech commerce present in Las Vegas subsequent week.
The Cambridge, Massachusetts-based firm mentioned it has created the world’s premier high-resolution fisheye sensor based mostly on optical metalens expertise. The tech signifies that design engineers may additional downsize cameras in superior driver-assistance methods (ADAS), AR/VR, UAVs, robotics, and industrial functions.
The surge in camera-based optical sensor applied sciences is driving 2Pi Optics’ work. The corporate’s patented expertise extends the metalens subject of view (FOV) to almost 180 levels with out compromising imaging high quality, outperforming conventional wide-FOV refractive optics in essential features resembling dimension, weight, efficiency, and cost-effectiveness.
On the core of the work lies the substitute of cumbersome and expensive standard wide-FOV lenses, comprised of a number of stacked lens items, with a single, slim, flat metalens. This tech permits the creation of ultra-compact, high-performance optical imagers and sensors. They may very well be utilized in functions resembling shopper electronics, automotive sensing, industrial inspection and biomedical analysis.
Established in 2021 as an offshoot from the Massachusetts Institute of Know-how, 2Pi’s founders have constantly pushed metalens expertise—a wafer-thin materials imbued with microscopic options that manipulate mild in exact methods. The corporate’s analysis has been patented.
Juejun Hu, a supplies science and engineering professor at MIT and CEO of 2Pi, mentioned in a press release, “As we speak’s refractive fisheye lenses, that are used to seize wide-angle, panoramic photos, have hit a design roadblock.”
Hu added, “They require between six and twelve stacked lens parts, which limits their compactness and affordability. Our design, in distinction, outperforms standard refractive, wide-FOV optics in all areas: dimension, weight, efficiency, and value. Higher nonetheless, 2Pi’s metalenses could be manufactured at wafer scale in standard semiconductor foundries.”
Numerous functions
AR/VR headsets: These cameras facilitate setting mapping, hand/eye monitoring, gesture, and facial recognition. The diminutive dimension and weight are notably advantageous for wearable units, and their expansive subject of view emulates human imaginative and prescient, heightening consumer immersion.
Automotive sensing: 2Pi’s expertise reduces the variety of sensors required for full 360-degree protection, enhancing the reliability and precision of ADAS whereas reducing computational overhead.
Robotics and drones: Light-weight, high-resolution imaging and 3-D depth sensors improve payload capability and increase goal identification accuracy.
Industrial inspection: Miniature machine imaginative and prescient cameras with excessive efficiency and low energy consumption provide versatile deployment, resembling borescope inspection cameras.
