Abstract
A wearable device includes a first optical sensor module, the first optical sensor module including: an image sensor configured to receive light from biological tissue; a photodiode configured to receive light from the tissue; a light source comprising a laser and being configured to illuminate, through the tissue, each of the image sensor and the photodiode, a distance between the image sensor and the photodiode being less than 50% of the distance between the image sensor and the light source; at least one processing circuit configured to process first data corresponding to a first light signal received by the image sensor from the light source to generate a speckleplethysmography (SPG) measurement, and to process second data corresponding to a second light signal received by the photodiode from the light source to generate a photoplethysmography (PPG) measurement.
