Abstract: An optical device may include an optical filter disposed over a first surface of one or more substrates. The optical filter may include an aperture and may be configured to pass light that is received via the aperture and that is associated with one or more wavelength ranges via the one or more substrates based on an angle of incidence of the light on the optical filter. The optical device may include one or more optical elements disposed over a second surface of the one or more substrates that are configured to direct light beams of the light that are associated with a particular wavelength range, of the one or more wavelength ranges, to a particular set of sensor elements of an optical sensor. The optical filter may include a thin film optical interference filter and the one or more optical elements may include one or more metamaterial structures.

Abstract: An optical filter may include a substrate. The optical filter may include a first mirror. The optical filter may include a second mirror. The optical filter may include a spacer. The first mirror, the second mirror, and the spacer may form a plurality of component filters. A first component filter, of the plurality of component filters, may be associated with a first cross-sectional area and a second component filter, of the plurality of component filters, is associated with a second cross-sectional area. The first cross-sectional area and the second cross-sectional area may be configured to response balance the first component filter and the second component filter.

Abstract: 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.

Abstract: An optical channel, of an optical filter, passes light associated with a particular wavelength range to a sensor element, of an optical sensor, that operates in a gated mode. One or more processors obtain, from the optical sensor, a first optical measurement and a second optical measurement related to a multi-layered subject. The first optical measurement indicates an amount of light associated with the particular wavelength range that the sensor element accumulated during a first time range, and the second optical measurement indicates an amount of light associated with the particular wavelength range that the sensor element accumulated during a second time range. The first time range is a subrange of the second time range. The one or more processors process the first optical measurement and the second optical measurement to determine one or more parameters associated with the multi-layered subject.

Abstract: An optical sensor device may include an optical sensor that includes a set of sensor elements; an optical filter that includes one or more channels; a phase mask configured to distribute a plurality of light beams associated with a subject in an encoded pattern on an input surface of the optical filter; and one or more processors. The one or more processors may be configured to obtain, from the optical sensor, sensor data associated with the subject and may determine a distance of the subject from the optical sensor device. The one or more processors may select, based on the distance, a processing technique to process the sensor data, wherein the processing technique is an imaging processing technique or a spectroscopic processing technique. The one or more processors may process, using the selected processing technique, the sensor data to generate output data and may provide the output data.

Abstract: A sputtering system may inject hydrogen and a sputtering gas into a chamber of the sputtering system, which may cause at least one layer of a hydrogenated semiconductor material, such as hydrogenated silicon (Si:H), to be sputtered onto a substrate disposed in the chamber until the at least one layer has a thickness that satisfies a threshold. In some implementations, the hydrogen and the sputtering gas may be injected into the chamber of the sputtering system while a temperature in the chamber is in a range from 145 degrees Celsius to 165 degrees Celsius. Accordingly, in some implementations, the sputtered layer of the hydrogenated semiconductor material may have one or more optical properties that satisfy a threshold to enable operation in a 9xx nanometer wavelength regime and at larger wavelengths.
