Title: Innovations by Alex Chalmers in X-ray Backscatter Technology

Introduction

Alex Chalmers is an accomplished inventor based in Norwood, MA (US). He has made significant contributions to the field of inspection systems, particularly through his innovative work in X-ray backscatter technology. With a total of 4 patents to his name, Chalmers has developed advanced solutions for inspecting objects and individuals using penetrating radiation.

Latest Patents

Chalmers' latest patents include the X-ray backscatter detection imaging modules and the X-ray backscatter mobile inspection van. The X-ray backscatter detection imaging modules are designed as an inspection system that utilizes an imaging enclosure characterized by an enclosing body. This system includes a source of penetrating radiation and a spatial modulator for forming the radiation into a beam, all concealed within the body of an enclosure, such as a shipping container. This design allows for convenient operational deployment. The system forms images based on scatter signals and relative motion signals, with a detector that may be sensitive to decay products of radioactive material.

The X-ray backscatter mobile inspection van is another innovative system developed by Chalmers. This enclosed conveyance is capable of road travel and is designed for inspecting persons or objects. Similar to the imaging modules, this system contains a source of penetrating radiation and a spatial modulator entirely within the body of the van. It employs a time-variable scanning profile to irradiate the inspected object, generating scatter signals that help form images of the contents based on the relative motion of the conveyance and the object.
