摘要： A photonic system includes a light source and a photonic structure. The photonic structure includes an optical transmission structure and an optical absorption structure. The optical transmission structure is configured to transmit light associated with a first wavelength range. The optical absorption structure is configured to absorb light associated with a second wavelength range. The light source is configured to provide a light beam with a wavelength that is within the second wavelength range to the optical absorption structure. The optical absorption structure is configured to generate and provide heat to the optical transmission structure when the light beam falls incident on the optical absorption structure.

摘要： An optical filter includes a first mirror that has a first uniform thickness, a second mirror that has a second uniform thickness, and a spacer that is positioned between the first mirror and the second mirror. The spacer has a variable thickness along a first axis of the optical filter. In some implementations, a thickness profile of the spacer, along the first axis, includes one or more portions that have a non-linear slope with an absolute value that is greater than zero.

摘要： An optical device includes an optical sensor, one or more diffusive optical elements disposed on a surface of a display screen and configured to diffuse and to distribute a first portion of light associated with a subject across an array of sensor elements of the optical sensor, and one or more processors. The display screen includes one or more transmissive components that allow the first portion of light to pass through the display screen via the surface of the display screen, and one or more blocking components that prevent a second portion of light associated with the subject from passing through the display screen. The one or more processors are configured to obtain, from the optical sensor, sensor data associated with the first portion of light, process the sensor data to determine an image of the subject, and perform one or more actions based on the image of the subject.

摘要： A multi-sensor device may perform an optical measurement using an optical sensor of the multi-sensor device, where the optical measurement is performed when a surface of the multi-sensor device is in contact with a human body. The multi-sensor device may perform another measurement using at least one other sensor of the multi-sensor device, where the other measurement is performed when the surface of the multi-sensor device is in contact with the human body, where the other measurement is performed substantially contemporaneously with the optical measurement, and where the optical measurement and the other measurement relate to health parameters. The multi-sensor device may determine a combined measurement value based on the optical measurement and the other measurement.
