Mechanically simplified, high resolution, optical focusing and steering apparatus

摘要

A method and apparatus for focusing a free beam of light onto a target. The target is often very small or angle restricted. The apparatus includes a lens surrounded by two parallel windows. The focusing of the free beam is achieved by tilting the first window to orient the beam of light through the lens onto the target, adjusting the lens focus to focus the beam of light into a focused spot, and tilting the second window to translate the focused spot across the target. The lens may also be tilted to provide a greater range of translation.
