Meta-optical spectral imaging via computation for lightweight hyperspectral imaging

Tunoptix will utilize meta-optical components paired with a dielectric color filter to produce a narrowband, high signal-to-noise ratio (SNR), and high field of view (FOV) light detection and ranging (LIDAR) system in the green wavelengths with a 100 mm aperture. This system will consist of two meta-optics, a collimation lens and a focusing lens that are integrated with a laser linewidth dielectric filter. The meta-optic collimation lens will consist of a matrix of individual meta-optic in an array. When compared with traditional solutions, the meta-optic solution will exhibit lower system complexity, size, and weight. In the base proposal, a scaled down version of the final meta-optics will be demonstrated and tested both component-wise and integrated as a system. Tunoptix will determine the etendue-limited performance bound and optimize the meta-optics to approach it. Following the base, option 1 will be the fabrication and characterization of the full 100 mm aperture meta-optic. In option 2, Tunoptix will utilize the multiplexed design of the meta-optic, asymmetries in the design, and computational imaging techniques to determine the angular spectrum of the incident light.
