摘要： A diffraction analysis device and a method for a full-field X-ray fluorescence imaging analysis are disclosed. The device includes a switching assembly, collimation assemblies, an X-ray source, an X-ray detector, a laser indicator, and a computer control system. The switching assembly combines with the collimation assemblies to achieve a functional effect that is previously achieved by two different types of devices through only one device by changing the positioning layout of the X-ray source and the X-ray detector. The full-field X-ray fluorescence imaging analysis can be realized, and the crystal phase composition information and the element distribution imaging information of the sample can be quickly obtained through the same device without scanning, which not only greatly improves the utilization rate of each assembly in the device, reduces the assemblies cost of the device, makes the device structure more compact, but also greatly improves the analysis efficiency and detection accuracy.
