摘要：<p>An optical system for a laser beam scanner, is capable of reducing the manufacturing cost by substituting a holographic optical element (10) for a toric lens, comprising a light source (11) for generating a laser beam (8), a rotary polyhedron (14) for collimating the laser beam (8) from the light source (11) and focusing and reflecting the laser beam; and a compensating lens array, including a concave lens (15) for receiving the laser beam from the rotary polyhedron (14) and a convex (16) lens attached with a holographic optical element (10), for compensating the laser beam reflected from the rotary polyhedron and scanning the compensated laser beam to a drum (17). <IMAGE></p>
