1. A method, comprising:
identifying, by a sensor device, a plurality of measurement locations based on whether a type of measurement that is to be performed is associated with a sub-surface type of measurement location or a surface type of measurement location,
wherein a first measurement location and a second measurement location, of the plurality of measurement locations, are identified based on the type of measurement that is to be performed is associated with the sub-surface type of measurement location;
obtaining, by the sensor device, first image data using a wavelength, associated with a near-infrared range, that penetrates to the first measurement location;
obtaining, by the sensor device, second image data regarding the second measurement location,
wherein the first measurement location and the second measurement location are different sub-surface measurement locations within a same blood vessel; and
providing, by the sensor device, information identifying a pulse transit time measurement based on the first image data and the second image data.
