ABSTRACT:
A disclosed device for optically scanning a target surface includes a light source unit configured to emit a light beam; a light intensity detecting unit; a coupling unit configured to substantially collimate the emitted light beam; a beam limiting unit configured to limit the amount of the collimated light beam; a beam splitting unit configured to split the beam limited light beam and thereby to cause a first portion of the beam limited light beam to enter the light intensity detecting unit, wherein the light intensity detecting unit is configured to detect the intensity of the first portion of the beam limited light beam; and a beam deflecting unit configured to deflect a second portion of the split light beam toward the target surface. In the disclosed device, the beam limiting unit and the beam splitting unit are integrated as a single unitary structure and positioned between the coupling unit and the light deflecting unit.
