Abstract
A method and apparatus that identify a composition of an object using a non-contact chemical sensor provided. The method includes detecting an object based on information provided by a plurality of sensors, transmitting a chemical detection signal, from a non-contact chemical sensor, at the detected object, identifying a composition of the detected object based on an attenuation of the chemical detection signal, determining whether a path change is required based on the identified composition of the detected object, and controlling one or more actuators to stop a vehicle or adjust the path of the vehicle if the path change is required.
