摘要：
A laser beam scanner comprises a scanning window (4) through which scanning beams are emitted, a plurality of hologram layers (41,42) constituting the scanning window, and an optical system for impinging a laser beam on the hologram layers in a manner such that the trace of the laser beam scanning each hologram layer intersects that of the other hologram layers on the scanning window. Such a laser beam scanner can be more compact as compared with conventional laser beam scanners.
