Abstract
A presence detection system (700) configured to detect a presence of a window (130) or a mirror (330) is disclosed. The system comprises a time-of-flight sensor (110, 310, 610) configured to detect a proximity to a target (105, 305, 605) based on reflected radiation sensed from a plurality of zones (620a-i). The system also discloses processing circuitry (750) configured to determine a presence of a mirror or window in a path from the time-of-flight sensor to the target based on one or more peaks in data corresponding to the sensed radiation reflected from each of the plurality of zones. A corresponding method of detecting a presence of a window or a mirror using the disclosed system is also disclosed.
