SBIR Phase II: Non-destructive Evaluation For Seismic Damage Assessments Using Real-Time X-Ray or Gamma-Ray Imaging System

这个小型企业创新研究二期项目将开发一种便携式、有效、低成本和易于使用的硬x射线或伽马射线检测系统，用于结构损伤评估。快速有效的室内和现场结构损伤无损评估对地震研究具有重要意义。在第一阶段，使用CSL高灵敏度，直接光子电子转换x射线图像系统的概念设计展示了一种新的实时非破坏性混凝土结构损伤测量技术，其空间分辨率为14 lp/mm。这项新技术将发展为硬x射线或伽马射线图像检测和处理系统，直接可视化和量化结构损伤，包括损伤位置、损伤模式和尺寸。通过这种快速硬x射线或伽马射线探测器和相关的图像传输网络系统，可以监测、记录和传输实时损坏过程。CSL将与SLNY Buffalo的国家地震工程研究中心一起进行一系列实验，以量化原型系统的主要设计参数，并证明这种新技术的可行性。该系统将有利于土木工程结构（包括桥梁，公用事业结构，老化学校以及住宅建筑）的检查和实时监测。

This Small Business Innovation Research Phase II project will develop a portable, effective, low cost and easy to use hard X-ray or gamma-ray inspection system for structural damage assessment. Quick and effective laboratory and field nondestructive evaluation of structural damage is important for earthquake studies. In Phase I, a conceptual design using the CSL high sensitivity, direct photon-electron conversion X-ray image system demonstrated a novel real-time nondestructive structural damage measurement technique for concrete with a spatial resolution of 14 lp/mm. This new technique will be developed to a hard x-ray or a gamma-ray image detecting and processing system to directly visualize and quantify the structural damage, including damage location, damage pattern and sizes. A real-time damaging process can be monitored, recorded and transferred by this fast hard X-ray or gamma-ray detector and the associated image transfer network system. Together with the National Center for Earthquake Engineering Research at SLNY Buffalo, CSL will conduct a series of experiments to quantify the major design parameters of the prototype system and to prove the feasibility of this novel technique This system will benefit the inspection and real-time monitoring of civil engineering structures including bridges, utility structures, aging schools, as well as residential buildings.
