Abstract
In optical scanning systems loss in spatial resolution can result in coupling systems incorporating off axis concave mirrors by virtue of image rotation. In such systems compensation can be introduced for this image rotation by inclining the axis of oscillation of the scanning mirror at a small angle to the plane of that mirror.
