Hybrid meta-optics to take professional grade pictures, yet fit right into the palm of our hands. How cool is this!
Modern smartphones and other smart-devices instead rely on computational imaging— using software to mask the shortcomings of their compact optical setup— to produce high-quality images and video., explore combining optics made from metamaterials and software.
The team addressed this drawback by employing a “hardware in the loop” strategy by experimenting with actual lenses and sensors instead of a software model, a move that the team attributes to have helped reduce the processing and memory demands. In the experiments, the researchers utilized a combination of hybrid meta-optics and computational imaging techniques to capture photographs of objects located at distances ranging from 0.5 to 1.8 meters.The hybrid meta-optics employed in their setup included a standard refractive lens measuring a thickness of 4.5 millimeters, coated with a quartz meta-optic film 500 µm thick.
“I believe the most impactful application at the moment is the design of a new generation of customized cameras for,” said Samuel Pinilla, lead study author, at the Science and Technology Facilities Council in Harwell, England, while noting the devices’ potential in biomedical applications. The team suggests developing meta-optics wider than their current 5 mm width could result in even better image quality by collecting more light.fit into our pockets isn’t too far off.The race for miniature color cameras using flat meta-optics has rapidly developed the end-to-end design framework using neural networks.
