An optical scanning system including an aiming system which is particularly suitable for handheld scanners where the outgoing light is scanned over a desired angle in a scan plane. The aiming system includes a light source generating an optical beam along an outgoing optical path toward an object to be scanned; a detector for detecting light reflected off the object; an oscillating scan mirror in the outgoing optical path directing light toward the object along a scan plane; and a diffractive optical module positioned in the outgoing optical path adjacent the scan mirror, the diffractive optical module having a pair of diffractive optical elements separated by an aperture, the diffractive optical elements positioned on either side of an aperture along the scan plane, each diffractive optical element de-scanning the portion of the optical beam passing therethrough to form an aiming light beam.
An aiming system for an optical data reading device, comprising: a light source generating an optical beam along an outgoing optical path toward an object to be scanned; a detector for detecting light reflected off the object; a scan mirror in the outgoing optical path directing light toward the obj
