The determination of the orientation parameters of a missile by means of a three-line scanner requires the generation of scanning traces which are oriented at a specific angle with respect to the direction of flight. In the present invention the scanning traces are produced with a two or four part scanning prism, whose reflecting surfaces are arranged at a specific angel .beta. with respect to the axis of rotation of the scanning prism.

DETAILED DESCRIPTION An object of the present invention is thus to provide a quadratic two or four part scanning prism which rotates about an axis of symmetry and which has at least one reflecting surface that is inclined at a specific angle .
beta.
with respect to the axis of rotation, the reflecting surface intersecting the axis of rotation near the middle of the prism.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
For a better understanding of the invention, its operating advantages and specific objectives attained by its use, reference should be had to the drawings and descriptive matter in which there is illustrated and described the preferred embodiments of the invention.
