Abstract
A system and method for calibrating speckle-based sensor. In some embodiments, the system includes a wearable device including: a laser, an array detector; and a processing circuit, the processing circuit being configured to: obtain a calibration of the array detector, using an incoherent light source; obtain a speckle image, using the laser; and calculate a corrected speckle-based measurement, the corrected speckle-based measurement being based on the speckle image and on the calibration.
