AI Technical Summary
Technical Problem
When traditional planar optical lenses are combined with high-bandwidth light sources, chromatic aberration is prone to occur, which limits the working spectral bandwidth of the imaging system and reduces its efficiency.
Method used
Employing a super-optical element (MOE) with distributed superatoms on its surface, it reduces chromatic aberration by separating light of different wavelengths at different angles in the field of view and adapting specific wavelength ranges in multiple regions of the superlens.
Benefits of technology
It enhances the operating spectral bandwidth of the imaging system, improves compatibility with standard light sources, and enhances the overall performance and efficiency of the imaging system.

Abstract
A system includes one or more elements configured to receive light of different wavelengths within a wavelength range from a light source and to separate the received light at different angles in a field of view based on the different wavelengths; an image sensor including a sensor surface; a superlens comprising a surface having a plurality of regions, where each region is configured to receive light incident within a respective range of angles of incidence, where each respective range of angles of incidence corresponds to a wavelength sub-range of split light, and where each region is configured to focus light from a respective wavelength sub-range on the sensor surface; and an optical aperture having an aperture size configured to limit a respective range of angles of incidence at each of the plurality of regions of the superlens.
