Abstract
A device for detecting a presence of an object includes an optical phased array, a detector, a processing portion and an indicator. The optical phased array can transmit a first optical beam to a first location at a first time and can transmit a second optical beam to a second location at a second time. The detector can detect a first reflected beam based on the first optical beam and can detect a second reflected beam based on the second optical beam. The processing portion can determine the presence of the object based on the first reflected beam and the second reflected beam. The indicator can generate an indicator signal based on the presence of the object.
