I am trying create a focal point of multiple parallel rays and move that point along a perpendicular plane somehow using the rotation of a lens or mirror via a galvanometer. It is a little hard to explain so I have included a diagram.

enter image description here

I understand that I could use a converging lens and rotate it to move the focal point, however this would move the point in a circular motion. Does anyone have any ideas on a setup where the focal point could be moved along the plane via rotation of a lens and/or mirror arrangement?

For anyone interested, I have found the type of lens I was after. It is called an f-theta scanning lens.
