Abstract: An optical filter includes a plurality of optical channels that each have a Fano resonance characteristic. A first optical channel, of the plurality of optical channels, is configured to pass a first portion of a first set of light beams (that are associated with a first wavelength range) and reflect a second portion of the first set of light beams when the first set of light beams falls incident on a particular surface of the first optical channel. A second optical channel, of the plurality of optical channels, is configured to pass a first portion of a second set of light beams (that are associated with a second wavelength range) and reflect a second portion of the second set of light beams when the second set of light beams falls incident on a particular surface of the second optical channel.

Abstract: A device may determine a time-of-flight measurement by performing a sample of a sensor based on light received via at least one first spectral filter, wherein the at least one first spectral filter is associated with a spectral range for a time-of-flight measurement; determine that a condition is satisfied with regard to the time-of-flight measurement, wherein the condition relates to an orientation or a position of the sensor or the sensor device relative to a measurement target; trigger a spectrometry measurement to be performed based on determining that the condition is satisfied with regard to the time-of-flight measurement; and perform, based on light received via at least one second spectral filter and by performing a sample of the sensor, the spectrometry measurement for the measurement target based on the condition being satisfied with regard to the time-of-flight measurement.

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: A device including an array of pixels and a filter wheel may capture a plurality of images by exposing the array of pixels. The device may spin, while capturing the plurality of images, the filter wheel, and the filter wheel may include filter segments. In some implementations, a portion of the filter wheel in front of the array of pixels includes two or more filter segments.

Abstract: A filter may include a substrate. The filter may include a stepped medium disposed on the substrate. The filter may include a first mirror disposed on the stepped medium. The first mirror may form a stepped mirror surface. Each step, of the stepped mirror surface may correspond to a channel, of a set of channels, of the filter. The filter may include a spacer disposed on the stepped mirror surface. The filter may include a second mirror disposed on another surface of the spacer.

Abstract: A waveguide includes a plurality of sets of layers arranged in a stack. Each set of layers includes a first layer that comprises at least tantalum and oxygen, and a second layer that comprises at least silicon and oxygen. The waveguide is configured to propagate light associated with a particular wavelength in a first direction that is orthogonal to a second direction in which the plurality of sets of layers are arranged in the stack. A quantity of the plurality of sets of layers is greater than or equal to 15. Respective thicknesses of the first layer and the second layer, in the second direction, are less than or equal to a fifteenth of the particular wavelength.

Abstract: A concealment component for an optical sensor device includes an optical filter and one or more diffusive optical structures. The one or more diffusive optical structures are configured to distribute light in a diffused pattern on an input surface of the optical filter. The optical filter is configured to pass a first set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are associated with a particular wavelength range, and prevent a second set of light beams, of the light distributed in the diffused pattern on the input surface of the optical filter, that are not associated with the particular wavelength range, from passing. Preventing the second set of light beams from passing is to cause the second set of light beams to be directed away from or absorbed by the concealment component in a concealment pattern.
