Abstract

U.S. Patent 4,247,I 60 - "Scanner with Reflective Pyramid Error Compensation", by Harry P. Brueggemann, issued January 27, 1981, discloses a method of obtaining wobble correction with cylindrical optical element without introducing cross-scan curvature. This was done by using a mirror instead of a glass lens, as disclosed in the patent but a mirror returns the rays in the direction that they came from and the possibility exists of interfering with other optical elements. Interference is avoided by tilting the mirror, as shown in Figures 2 and 4 of the patent,
