XRD Theory

Computer Integration

With the growing acceptance and availability of high power, low-cost computers, and advancements in automation equipment, it’s easy to see why the new breed of X-ray diffraction equipment is being integrated into fully automated systems. By computerizing these systems a new high level of resolution, accuracy and repeatability is achievable. Computer control provides full control over angular position and rotation of the goniometer as well as real-time feedback from the detection circuitry. By utilizing the computer and specialized software, multiple and simultaneously measurements of the goniometer position and detector output can be obtained. Highly accurate peak readings can be calculated by use of algorithmic equations and standard deviation incorporated into the software. Employing this type of computer diffraction system allows for resolution accuracy of ±5 arc seconds.
