CA 2021519

A integrated laser scanning device including: a substrate of semiconductor and/or electro-optical material, a laser light source disposed on the said substrate; and a scanner disposed on the substrate in the path of the laser beam for repetitively and cyclically moving the laser beam so as to form a scanning beam for repetitively scanning a target for reflection therefrom. In particular, the scanner comprises a layer of reflective material disposed on a moveable structure on the substrate, the plane of such layer being disposed at an acute angle with respect to the laser beam so that said beam is directed along an optical path toward indicia located in the vicinity of a reference plane lying in the optical path so as to scan spatially adjacent portions of the reference plane along a relatively elongated scanning line.
