A sensing arrangement for obtaining data from a body part using accurate reference values

Abstract

A sensing arrangement (100) for obtaining data from captured light reflected by, transmitted through, and/or modulated by a body part (110) of a person. The sensing arrangement comprises: illumination means (120) arranged to illuminate at least a portion of the body part (110); optical sensing means (130) arranged to capture light reflected by, transmitted through, and/or modulated by the body part (110); and a control unit (150) arranged to determine an identity of the person, determine one or more health parameters from the captured light, obtain, for at least one health parameter, a reference parameter associated with the person from a database, and determine a deviation of at least one health parameter from its corresponding reference parameter.
