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.
Key words：CuAz preservative；Bamboo；Synchrotron radiation；Dual energy subtraction imaging；Phase contrast imaging
