摘要
第三代同步辐射光源X射线具有高亮度、 光谱连续、 宽频谱范围、 高空间分辨率、 高衬度分辨率等独特优越性, 可实现光谱精准计算及能量可调, 对低Z材料内部结构边缘增强图像方面也具有很强的优势。 利用上海同步辐射光源X射线双能减影和相衬成像技术, 实现铜唑防腐剂处理竹材的同步辐射无损检测研究, 并获得了Cu的分布图和处理材的内部结构, 该技术为防腐处理竹材解剖学研究提供了一个重要无损检测手段。
Abstract
The third-generation synchrotron radiation X-ray has many advantages such as high brightness, continuous spectrum, wide spectral range, high spatial resolution and high resolution and so on, which helps to realize the adjustable energy and precise calculation of its spectrum. And it also has the competitive advantage of obtaining the edge enhancement image for high contrast imaging of low Z materials. In this paper, the Cu distribution was obtained by dual energy subtraction imaging and the characteristic microstructures of CuAz preservative treated bamboo were investigated systemically with XPCM at Shanghai Synchrotron Radiation Facility (SSRF).The results showed the testing techniques were expected to the important precision nondestructive methods for preservative treated bamboo.
