Structural Integrity Inspection and Visualization System, Phase I

Completed Technology Project

Project Introduction

Structural Integrity Inspection and Visualization System, Phase I
To address NASA's need for compact nondestructive evaluation (NDE) of the structural integrity of spacecraft components and structures, Physical Optics Corporation (POC) proposes to develop a new Structural Integrity Inspection and Visualization System (SIRIUS), based on acquiring two-dimensional images of Compton-scattered hard X-ray radiation produced by multiple slices of the object, with subsequent three-dimensional reconstruction of the inspected structure for high-resolution (~0.5 mm) detection and localization of defects. This approach incorporates the POC-developed innovative X-ray Compton Imaging Tomography technique (patent pending) and patented X-ray imaging optics with high spatial resolution and a wide field of view, enabling it to meet NASA's requirements for operation on a wide range of lightweight spacecraft materials, noncontact operation, portability, and ease of use. SIRIUS will provide detection and three-dimensional localization of defects and damage in space transportation vehicles, pressure vessels, ISS modules, inflatable structures, EVA suits, MMOD shields, and thermal protection structures, with spatial resolution of ~0.5 mm and penetration depth up to 25 cm (depending on the material). In Phase I POC will demonstrate the feasibility of using SIRIUS for NDE of spacecraft components by fabricating and testing a TRL-4 prototype, with the goal of achieving TRL-6 by the end of Phase II.
