An automatic beam scanning apparatus is disclosed in the patent wherein a cylindrical open-ended chamber houses an optical beacon for evaluation. The chamber is rotatable about its longitudinal axis for determining the beacon beam intensity at selectable points off the axis of rotation. The chamber also is traversable in a path which sweeps a beacon beam over a detector. Hence, a predetermined rotate and sweep arrangement allows detection of the spatial energy distribution of the beam of an optical beacon.
