Claim:
1. A light-scanning system comprising: a scanning mirror; at least two stationary mirrors with reflective surfaces angled toward the scanning mirror; an objective lens that includes a back plate with an aperture; and a redirection mirror, wherein the scanning mirror is positioned so that when a beam of light strikes the scanning mirror, the beam is to undergo at least seven reflections with a final reflection off of the redirection mirror that places the beam on a path through a pivot point in the aperture, and wherein two of the at least two stationary mirrors, the scanning mirror, and the redirection mirror are arranged so that a wave packet of the beam is to undergo a first reflection off of the scanning mirror, a second reflection off of a first stationary mirror, a third reflection off of a second stationary mirror, a fourth reflection off of the scanning mirror, a fifth reflection off of the first stationary mirror, a sixth reflection off of the scanning mirror, and a seventh reflection off of the redirection mirror that places the beam on a path through the pivot point in the aperture, in that order while the scanning mirror is in any single rotational angle within a range of angles utilized for scanning.
