Abstract:
Methods and apparatus for covert detection of an interrogating device. In one example a method includes receiving an interrogation beam at an optical system, imaging a scene including a source of the interrogation beam without retro-reflecting the interrogation beam to produce an image, and analyzing the image to determine an approximate location of the source within the scene. In some examples, a threat detection sensor is used to further analyze the interrogation beam to determine information about the interrogating device.
