<p>A device is provided for scanning a flat surface having a given orientation between two arbitrary orthogonal planes P and P'. The device comprises a carrier arm whereon a detector can slide and be orientated. The detector carrier arm is itself arranged to be slidable on an intermediate arm which constitutes, in conjunction with the detector carrier arm, a plane which is parallel to the plane P. A carrier arm, whereon the intermediate arm is arranged to be slidable, constitutes, in conjunction with the latter, the plane P" which is perpendicular to the planes P and P'. This carrier arm is capable of displacement in a plane parallel to the plane P'. The device offers lightness and mobility, and can notably be employed for apparatus for diagnostic examination by recording scintillations.</p> |
