1.1 Basic principles

The X-ray Orientation Analyzer penetrates the sample to be detected by x-rays and then maps an X-ray image on the image detector. The quality of the image is determined primarily by resolution and contrast.

The resolution of the imaging system depends on the size of the focal spot of the X-ray source, and currently detector pixels can detect objects of tens of microns.

1.2 X-ray tube

In an X-ray tube, electrons are accelerated from the hot cathode through an electric field to the anode. X-rays are released when the impact to the anode body is stopped. The size of the collision zone is the size of the X-ray source, usually in millimeters, in which case we do not get a clear image.
     By using a microfocus X-ray tube, electrons can enter the magneto-electronic lens through a small hole in the anode, the magnetic field force in the lens focusing the electron beam on a focal point of the cathode target that is only a few tens of microns in diameter. In this way, the X-ray source can be made small, and a sharp image with a resolution in the micrometer range can be obtained at a high magnification.

1.3 X-ray orientation analyzer

Digital photography reduces exposure and processing time, costs less (no film and chemical liquids), and no chemical waste, all of which cost significantly less. In addition, the digital image can be enlarged to improve the detection rate of defects, and in some cases, automatic evaluation can be used for the inspection results. Digital inspection results are transmitted from the field to the office for storage via wireless transmission, and the cost of storage is low.
