Abstract
A method for aligning an optical assembly, including the steps of emitting at least one beam from an emitter substantially along a first axis, disposing a cylindrical lens in said at least one beam to form at least one line image, wherein a longitudinal axis of said cylinder lens is substantially parallel to a second axis which is different from said first axis, displaying at least one vertical profile of said at least one line image, defocusing said at least one line image until a first peak and a second peak of said at least one profile are displayed and adjusting in a third axis which is different from said first axis and said second axis a position of said cylindrical lens relative to said emitter until said first peak and said second peak are symmetric.
