In analyzing the texture of rolled metal sheets and strips by means of X-rays or .gamma.-rays that penetrate them, the total beam emitted by the source of radiation is divided by collimators into several component beams, and each component beam is aimed at a different angle at a component area of the sheet or strip being tested. The diffracted radiation that penetrates the sheet is analyzed in accordance with its energy distribution in detectors and the results are processed in a computer.

Method and apparatus for texture analysis

To determine the thickness profile of rolled metal sheets by measuring the absorption of X-rays a slit diaphragm is used which is rotatable about the imaginary center axis of the X-ray tube, the rotation consisting of a reciprocating movement lying in a range of less than 36.degree.. Between the reversal points of the rotation the rotational movement takes place in steps with rest intervals lying therebetween.
