Summary:Title screen
The practice of non-destructive testing shows that despite the whole range of working standards that define the methods of measurement of µ-focus spot sizes, the consistency and spread of the obtained results are considered unsatisfactory. In the meantime, knowing the accurate size of µ-focus spot is the determinant factor in optimization of control parameters, which is often carried out with geometric magnification. A new design of test object is proposed, a new method of differentiated line profiles of test object digital image is developed and tested, the computing chain and allowances are described. The obtained results have formed the basis for elaboration of a Standard to measure µ-focus spot size of an X-ray tube.
