A disclosed vehicle sensing system includes an optic fiber disposed adjacent to a vehicle panel, a transmitter/receiver disposed at an originating end of the optic fiber, the transmitter/receiver configured to emit a beam through the optic fiber at a defined originating frequency, and a reflector disposed at a terminal end of the optic fiber for reflecting the beam back through the optic fiber to the transmitter/receiver. Dimensional changes to the optic fiber change the originating frequency reflected back to the transmitter/receiver and the change in the originating frequency is indicative of a physical change in the vehicle panel.
