Abstract
An optical foreign object detection (FOD) system for a gas turbine engine includes a multiple of emitters arranged about an inner periphery of a fan cowl, a multiple or receivers arranged about the inner periphery of the fan cowl, each of the multiple of receivers receiving a beam from one of the multiple of emitters to form a beam matrix; and a control system in communication with the multiple of emitters and the multiple of receivers, the control system operable to detect a minimum sized object in response to breaking at least one beam of the beam matrix.
