Abstract: Various aspects of the present disclosure generally relate to a multispectral sensor device. In some aspects, a sensor device may obtain, from image data collected by a sensor of the sensor device, first image data regarding a first measurement location of a measurement target, and may obtain, from the image data, second image data regarding a second measurement location of the measurement target, wherein the first measurement location and the second measurement location are sub-surface measurement locations within the measurement target. The sensor device may determine, based on the first image data and the second image data, a pulse transit time measurement, and provide information identifying the pulse transit time measurement. Numerous other aspects are provided.

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.
