In an embodiment, an apparatus includes a meta-optics lens having a point spread function. The meta-optics lens is configured to receive light associated with a scene and output transformed light. At least one value of at least one mathematical property of the transformed light is dependent upon a set of wavelengths associated with the transformed light. The apparatus further includes a processor configured to receive a representation of the transformed light. The processor is further configured to determine the at least one value of the at least one mathematical property of the transformed light using the representation of the transformed light. The processor is further configured to determine spectrum information associated with the scene based on the at least one value and the point spread function.

Optical meta-lens spectrometer to analyze spectral characteristics of light

In an embodiment, a system comprises a first camera including a first filter having a spectral response, a first meta-optic lens, and a first sensor. The system comprises a second camera including a second filter having a spectral response different than the spectral response of the first filter, a second meta-optic lens, and a second sensor. The system also comprises a processor configured to receive a representation of a first image of a scene captured by the first camera, receive a representation of a second image of the scene captured by the second camera, and generate a representation of a superposed image of the scene based on the representation of the first image and the representation of the second image, the representation of the superposed image having an aberration lesser than an aberration of the representation of the first image and an aberration of the representation of the second image.

Systems and methods for high quality imaging using a color-splitting meta-optical computation camera

Metasurfaces and systems including metasurfaces for imaging and methods of imaging are described. Such metasurfaces may be formed on a substrate from a plurality of posts. The metasurfaces are configured to be optically active over a wavelength range and in certain embodiments are configured to form lenses. In particular, the metasurfaces described herein may be configured to focus light passed through the metasurface in an extended depth of focus. Accordingly, the disclosed metasurfaces are generally suitable for generating color without or with minimal chromatic aberrations, for example, in conjunction with computational reconstruction.

Metasurfaces for full-color imaging

Disclosed herein are metasurfaces formed on a substrate from a plurality of posts. The metasurfaces are configured to be optically active at one or more wavelengths and in certain embodiments are configured to form lenses having unexpectedly strong focusing power. In particular, the metasurfaces are formed from 'low-contrast' materials, including CMOS-compatible materials such as silicon dioxide or silicon nitride. Accordingly, the disclosed metasurfaces are generally CMOS compatible and therefore embody a new paradigm in metasurface design and manufacturing.
