The image quality of this salt-grain-sized camera in the United States is better than that of your mobile phone?

Full-Color Imaging with Learned Meta-Optics

Meta-optics—2-D arrays of subwavelength scatterers—have recently emerged as a promising candidate for drastically miniaturizing image sensors.1 Like any diffractive optics, however, meta-optical lenses suffer from strong chromatic aberrations. As such, full-color images captured by a single meta-optic have remained poor, limiting their applications in imaging. We recently demonstrated that combining computer learning algorithms with meta-optics can […]

Researchers shrink camera to the size of a salt grain

Researchers at Princeton University and the University of Washington have developed an ultracompact camera the size of a coarse grain of salt. The system relies on a technology called a metasurface, which is studded with 1.6 million cylindrical posts and can be produced much like a computer chip.  Now, researchers at Princeton University and the […]
