The Takeaway
Standard X-ray imaging would reveal a warhead's top-secret internal blueprints, making it impossible to use in disarmament treaties. This method uses a single-pixel detector to 'fingerprint' the weapon's density without ever creating an actual image, allowing inspectors to confirm a bomb is real without seeing its classified secrets.
From the abstract
In nuclear arms control and disarmament processes, it is crucial to determine whether an object is a nuclear weapon or not without revealing sensitive information about it. At the MIT: Laboratory for Nuclear Security and Policy, such a nuclear verification method was developed, showcasing a transmission-based approach [1]. This method's essential part rests on a mathematical operation, the Single-Pixel X-Ray Transform: a cone of X-rays transmits an object and the remaining intensity is measured
