Publication number: 20090257555Abstract: An inspection system, and inspection methods, based upon an imaging enclosure characterized by an enclosing body. A source of penetrating radiation and a detector module are concealed entirely within the body of a conveyance such as a trailer. A characterizing value or an image is formed with respect to an inspected object that is disposed entirely outside the conveyance and the characterizing value or image is made available to a remotely disposed operator. Additional detectors may be disposed distally to the inspected object and may detect transmitted, or forward-scattered, penetrating radiation.Type: ApplicationFiled: February 10, 2009Publication date: October 15, 2009Applicant: American Science and Engineering, Inc.Inventors: Alex Chalmers, Louis W. Perich, Peter J. Rothschild, William John Baukus, Jeffrey Schubert

Patent number: 7505556Abstract: An inspection system based upon an imaging enclosure characterized by an enclosing body, or skin. A source of penetrating radiation and a spatial modulator for forming the penetrating radiation into a beam, are both concealed entirely within the body of an enclosure such as a shipping container for convenient operational deployment. Multiple modules, such as for providing power and for enclosing an operator console may be coupled to the imaging enclosure. An image is formed of the contents of the object based in part on the scatter signal and the relative motion signal. A detector, which may be separate or part of the scatter detector module, may exhibit sensitivity to decay products of radioactive material.Type: GrantFiled: December 11, 2006Date of Patent: March 17, 2009Assignee: American Science and Engineering, Inc.Inventors: Alex Chalmers, Louis W. Perich, Peter Rothschild, William John Baukus

Patent number: 7218704Abstract: An inspection system based upon an enclosed conveyance such as a van, capable of road travel, for inspecting persons or objects. The conveyance is characterized by an enclosing body, or skin. A source of penetrating radiation and a spatial modulator for forming the penetrating radiation into a beam, both contained entirely within the body of the enclosed conveyance, irradiate the person or object with a time-variable scanning profile. A detector module generates a scatter signal based on the scatter of penetrating radiation. A proximity sensor may be employed to generate a relative motion signal based on a relative disposition of the conveyance and the inspected object. An image is formed of the contents of the object based in part on the scatter signal and the relative motion signal. A detector, which may be separate or part of the scatter detector module, may exhibit sensitivity to decay products of radioactive material.Type: GrantFiled: September 29, 2005Date of Patent: May 15, 2007Assignee: American Science and Engineering, Inc.Inventors: William L. Adams, Alex Chalmers, Lee Grodzins, Louis W. Perich, Peter Rothschild

Patent number: 6658087Abstract: An apparatus for inspecting a physical object in a nautical environment includes a radiation source capable of directing a beam of penetrating radiation toward the physical object, and a detector capable of detecting the reaction of the physical object to the penetrating radiation. In addition to detecting the reaction, the detector is capable of delivering an output signal characterizing the physical object. Accordingly, the output signal is based upon the reaction of the physical object to the penetrating radiation.Type: GrantFiled: May 2, 2002Date of Patent: December 2, 2003Assignee: American Science and Engineering, Inc.Inventors: Alex Chalmers, Charles Squires
