Abstract
PURPOSE: To reduce the distortion of a projected image and enhance the accuracy in reference to the rotation of a reflecting mirror in the galvanometer, etc., by scanning the light ray by the combination of a concave reflecting mirrow and a concave mirror rotatable around two axes orthogonal each other with the focus as its center.
