Full-color imaging with a large aperture meta-lens remains an important unsolved problem. We employ computationally designed meta-optics to solve this problem and enable ultra-compact cameras. Our solution is to design the meta-optics such that the modulation transfer function (MTF) of all the wavelength across the desired optical bandwidth are the same at the sensor plane. Additionally, the volume under the MTF curve is maximized to ensure enough information is captured enabling computational reconstruction of the image. The same intuition can be employed for different angles to mitigate geometric aberrations as well. In this talk, I will describe our efforts on achieving full-color imaging using a single meta-optic and a computational backend. Starting from traditional extended depth of focus lens, I will describe inverse-designed meta-optics, end-to-end designed meta-optics and hybrid refractive/ meta-optics for visible full-color imaging. I will also talk about how these techniques can be extended for thermal imaging.
