Resonant galvanometer scanner assembly |
摘要 |
A hardware packaging assembly for a galvanometer optical beam scanning apparatus includes an optical component-containing portion having a light source aperture through which the output beam from the ILD that carries the to be recorded data passes. This aperture is disposed in a wall defining a boundary of the interior of the housing. Light from the ILD is reflected off a fixed mirror disposed adjacent to an opposite wall and is directed to a galvanometer scanning mirror. As the mirror is rotated about a longitudinal axis, it scans the ILD output beam across an output (image correction) lens mounted in the housing. A second opening disposed in the rear wall of the housing interior receives a start-of-scan photodetector element, which is positioned to detect light that is back-reflected off the inner face of the lens at a prescribed angle of sweep of the beam by the galvanometer mirror.
