Abstract:
1. An image compensation method, comprising: providing a light source to produce light having a first color content; providing a carrier having a plurality of grooves formed thereon and a plurality of reflecting elements disposed thereon, wherein the grooves are formed on the surface of the carrier and the reflecting elements are disposed on surfaces of the carrier inside the grooves, wherein the light source is disposed in a first one of the grooves, and each reflecting element is arranged, if aligned with the light source, to reflect at least a portion of the produced light from the light source to produce a beam of light biased towards a second color content different from the first color content, wherein reflecting elements are arranged to direct the reflected beam of light to a scanning location; moving either the carrier or the light source so that the light source is displaced from the groove; rotating the carrier so that a second different one of the grooves aligns with the light source; and moving either the carrier or the light source so that the light source is disposed in the second groove.
