Beam shapers (170), imaging heads formed using such beam shapers (170) and methods are provided that are adapted to shape a light beam for use in imaging. In accordance with one method described herein a light beam is received and the light beam is reflectively scrambled by the multimode optical path having a noncircular core of the beam shaper (170) to form generally homogenous light having a non-circular shape. The homogenous light is delivered to a circular core multimode light path (130) that shapes the light beam so that light exiting the circular core multimode light path comprises circular shaped homogenous light.
