Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-retro-reflective optical threat detection system comprising: a structured relay optic configured to receive electromagnetic radiation representing a source image volume, the electromagnetic radiation including an interrogation beam, the structured relay optic further configured to slice the source image volume into a plurality of image slices and to reimage the plurality of image slices onto a tilted image plane that is tilted relative to an optical ax…
