Abstract
A method includes transmitting first optical energy towards a space being scanned. The method also includes detecting one or more instances of a first material in the space using first return optical energy, where the first return optical energy is based on the transmitted first optical energy. The method further includes, for each of the one or more instances of the first material, transmitting second optical energy towards a portion of the space in which the instance of the first material was detected. The method also includes detecting one or more instances of a second material in the space using second return optical energy, where the second return optical energy is based on the transmitted second optical energy. In addition, the method includes identifying a presence of at least one type of device in the space based on instances of the first and second materials detected in the space.
