of the two scan mirrors is shown.
From the standpoint of the optics, there is one major limitation to this approach. This is that most
scan lenses are designed to cover a "flat…

again, heat builds up and fast scanning or parallel processing is often beneficial.
Thus, systems that provide fast and high-accuracy
