Method and system for estimating physiological information via set of LEDs and photodetectors by determining a correction profile based on a ratio

Abstract

The present disclosure provides a method for estimating physiological information performed by at least one processor. This method may include: receiving, by photodiodes, a first optical data set associated with light irradiated by plural light emitting diodes (LEDs) to a first substance; receiving, by the photodiodes, a second optical data set associated with light irradiated by the plural LEDs to a second substance; calculating first correction data associated with the plural LEDs based on the first optical data set and the second optical data set; calculating second correction data associated with the plural LEDs based on the first correction data and profile data associated with the plural LEDs; and estimating physiological information associated with the second substance based on the first correction data and the second correction data.
