Short standoff checkpoint detection system
First Claim
1. A method of detecting characteristics of a test subject at a checkpoint, the method comprising:
- exposing a single test subject to electromagnetic radiation at a security checkpoint;
determining how the electromagnetic radiation interacts with different portions of the single test subject;
determining different material properties for the different portions of the single test subject by examining how the electromagnetic radiation interacts with the different portions of the single test subject, wherein determining different material properties comprises detecting wavelength shifts of the electromagnetic radiation; and
providing an indication of the different material properties of the different portions of the single test subject, wherein providing an indication of the different material properties of the different portions of the single test subject comprises distinguishing between different material properties.

Abstract
Detecting characteristics of a test subject at a checkpoint. Embodiments may include exposing a single test subject to electromagnetic radiation at a security checkpoint. They may further include determining how the electromagnetic radiation interacts with different portions of the single test subject. They may further include determining different material properties for the different portions of the single test subject by examining how the electromagnetic radiation interacts with the different portions of the single test subject. They may further include providing an indication of the different material properties of the different portions of the single test subject, wherein providing an indication of the different material properties of the different portions of the single test subject comprises distinguishing between different material properties.

17. A system for detecting characteristics of a test subject at a checkpoint, the system comprising:
-
one or more processors; and one or more computer readable media, wherein the one or more computer readable media comprise computer executable instructions that when executed by at least one of the one or more processors cause at least one of the one or more processors to perform the following; exposing a single test subject to electromagnetic radiation at a security checkpoint; determining how the electromagnetic radiation interacts with different portions of the single test subject; determining different material properties tbr the different portions of the single test subject by examining how the electromagnetic radiation interacts with the different portions of the single test subject wherein determining different material properties comprises detecting wavelength shifts of the electromagnetic radiation; and providing an indication of the different material properties of the different portions of the single test subject, wherein providing an indication of the different material properties of the different portions of the single Lest subject comprises distinguishing between different material properties.

18. A system for detecting characteristics of a test subject at a checkpoint, the system comprising:
-
one or more transmitters configured to expose a single test subject to electromagnetic radiation at a security checkpoint; one or more receivers configured to capture at least a portion of the electromagnetic radiation; and one or more processors coupled to the one or more receivers, the one or more processors configured to; determine how the electromagnetic radiation interacts with different portions of the single test subject; determine different material properties for the different portions of the single test subject by examining how the electromagnetic radiation interacts with the different portions of the single test subject wherein determining different material properties comprises detecting wavelength shifts of the electromagnetic radiation; and provide an indication of the different material properties of the different portions of the single test subject, wherein providing an indication of the different material properties of the different portions of the single test subject comprises distinguishing between different material properties.
