Abstract: In some implementations, a system may obtain image data associated with a scene. The system may obtain multispectral data associated with the scene. The system may identify one or more objects depicted by the image data. The system may determine representative optical properties of the one or more objects. The system may identify, based on at least one of the image data or the multispectral data, captured optical properties of the one or more objects. The system may generate a color corrected image. The system may provide the color corrected image to a user device for display by the user device.

Abstract: In some implementations, an optical element comprises a glass substrate, a dark mirror coating disposed on a first surface of the glass substrate, and a lens disposed on a second surface of the glass substrate. An aperture is formed in the dark mirror coating, and the aperture is aligned with the lens. The optical element is a monolithic optical element.

Abstract: An optical device includes an optical sensor, a dye-based optical filter, and a multi-bandpass optical interference filter. The multi-bandpass optical interference filter is configured to pass a first spectral range of visible light, a second spectral range of visible light, and a third spectral range of visible light. The second spectral range does not overlap with the first spectral range, and the third spectral range does not overlap with the first spectral range and the second spectral range. The multi-bandpass optical interference filter is further configured to prevent passage of a fourth spectral range of near-infrared light. An angle shift associated with each spectral range, of the first spectral range, the second spectral range, and the third spectral range, is less than or equal to 2.0% of a center wavelength of the spectral range for angles of incidence between 0 and 30 degrees.

Abstract: In some implementations, an optical filter includes a first set of layers configured to pass light associated with a first wavelength range; a second set of layers configured to reflect light associated with at least one subrange of the first wavelength range; and a third set of layers configured to reflect light associated with a second wavelength range. In some implementations, the first wavelength range comprises an upper wavelength cutoff associated with a wavelength threshold, and the second wavelength range comprises a lower wavelength cutoff associated with the wavelength threshold. In some implementations, the optical filter includes a fourth set of layers configured to absorb a particular percentage of light in the first wavelength range.
