摘要： An optical detector device may receive a spectroscopic measurement from a multispectral sensor. The optical detector device may determine, based on the spectroscopic measurement, a particulate size of a particulate. The optical detector device may determine, based on the spectroscopic measurement, an identification of the particulate. The optical detector device may determine, based on the particulate size and the identification of the particulate, that an alert condition is satisfied. The optical detector device may trigger an alert based on determining that the alert condition is satisfied.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An optical interference filter includes a substrate and one or more sets of layers that are disposed on the substrate. Each set of layers includes a first layer that comprises at least scandium, aluminum, and nitrogen, and a second layer that comprises at least silicon and oxygen. The first layer may comprise at least one of a scandium aluminum nitride (ScAlN) material or a scandium aluminum nitrogen oxide (ScAlNO) material. The second layer may comprise a hydrogenated silicon (Si:H) material. An absolute value of a net stress of the one or more sets of layers may be less than or equal to 50 megapascals.

摘要： An optical sensor device includes an optical filter, an optical element, and an optical sensor that includes a plurality of sensor elements. The optical filter is configured to pass, to the optical element, first light beams that are associated with a first subrange of a spectral range and that impinge on the optical filter within a first incidence angle range; and to pass, to the optical element, second light beams that are associated with a second subrange of the spectral range and that impinge on the optical filter within a second incidence angle range. The optical element is configured to cause, based on receiving the first light beams, the first light beams to be directed to a first region of an optical sensor; and to cause, based on receiving the second light beams, the second light beams to be directed to a second region of the optical sensor.

摘要： In some implementations, an optical device may include an aperture, one or more optical elements, an optical filter, and an optical sensor. The aperture may be configured to receive light. The one or more optical elements may be configured to diffuse the light received by the aperture, direct the diffused light to the optical filter via a folded optical path, wherein a length of the folded optical path is greater than a distance between the aperture and an input surface of the optical filter, and cause the diffused light to be distributed across the input surface of the optical filter. The optical filter may be configured to filter the diffused light distributed across the input surface of the optical filter to pass portions of the diffused light associated with one or more wavelengths to the optical sensor.
