Various aspects of the present disclosure relate generally to multispectral sensor devices. In some aspects, the sensor device may obtain, from image data collected by a sensor of the sensor device, first image data relating to a first measurement location of the measurement target, from the image data to a second measurement location of the measurement target. may acquire second image data about the measurement position, wherein the first measurement position and the second measurement position are measurement positions below the surface in the measurement target. The sensor device may determine, based on the first image data and the second image data, the pulse transit time measurement, and may provide information identifying the pulse transit time measurement. Numerous other aspects are provided. |
