Abstract:
A method of correcting angle error in a pattern scanned onto a medium, the method comprising:scanning a beam along a scan axis and onto a first reflective surface of a first reflective element;directing the beam reflected from the first reflective surface of the first reflective element onto the first reflective surface of a second reflective element that is substantially parallel to the first reflective surface of the first reflective element;directing the beam reflected from the first reflective surface of the second reflective element to a second reflective surface of the second reflective element and subsequently to a second reflective surface of the first reflective element;inclining the second reflective element relative to the first reflective element; anddirecting the beam reflected from the second reflective surface of the first reflective element towards the medium.
