A method is described which allows to measure pole figures under the condition of constant information depth. This is achieved by using ω- and χ-tilt simultaneously. In order to obtain satisfactory integrated intensities the use of a position sensitive detector is nearly indispensable. The functional relationship between ω and χ for constant information depth and the transformation of Euler angles {ϕ1,φ,ϕ2} to pole figure angles {α β} are given as well as the necessary intensity correction. The use of ω-tilt leads to blind areas in the centre of pole figures which can, however, be compensated by increasing the number of pole figures and using appropriate ODF programs.

The method was tested with composite samples obtained by stacking aluminium foils with known textures but with exchanging rolling and transverse direction of the uppermost foil. The results will be shown in the second part of the paper.
