ABSTRACT:
An object-space scanning system for radiation wherein the scanning device comprises sets of planar reflecting surfaces arranged in pairs, one from each set, such that the two surfaces in a pair are disposed substantially at right angles to each other and the line of intersection of the surfaces is at right angles to the axis of rotation of the scanning device which is so arranged that incident radiation is sequentially reflected from the two surfaces of a pair before entering a focussing arrangement which focusses the radiation into a detector, the secondary scan direction being achieved by the fact that the angle included between the planar reflective surfaces of respective pairs differs by a very small angle successively around said axis.
