Abstract:
A laser imaging apparatus, comprising:a light source unit that emits a laser beam including a first beam and a second beam, central axes of the first and second beams substantially coinciding with each other, the first beam including non-visible light, the second beam including visible light; a modulating optical system that modulates the beam emitted by said light source unit, the first beam configured to form an image on the surface to be scanned, the second beam being configured to align the modulating optical system by adjusting a positional relationship of the first beam with respect to the optical axis of the modulating optical system; a deflector that deflects the beam modulated by said modulating optical system, the deflected beam scanning within a predetermined angular range; and an imaging optical system that converges the deflected beam to form a scanning beam spot on a surface to be scanned.
