Abstract
A device that includes a projection element positioned between first and second beam scanners configured in series and a two-dimensional display plane. An apparatus for controlling the first and second beam scanners is provided so that the angle of incidence and the point of incidence of a beam output from the series connected beam scanners onto the projection element are controlled. In that manner, each point on the projection element can be mapped to a line in the display plane. A method of mapping a point in the projection element to a line in the display plane is also disclosed.
