1. A method for creating a pixel image in a two-dimensional rectangular display coordinate system from sampled data derived from a collector of a scanned beam imager having an oscillating reflector, wherein the reflector has a surface, wherein the reflector has substantially orthogonal first and second axes of rotation, wherein the reflector oscillates in a resonant mode about the first and second axes of rotation causing a beam of radiation reflected from the surface to trace a substantially Lissajous trajectory in a two-dimensional acquisition coordinate system, wherein the Lissajous trajectory contains datum locations in the acquisition coordinate system associated with the sampled data, wherein the reflector has a third axis of rotation substantially orthogonal to the first and second axes of rotation of the reflector, and wherein the method comprises: a) receiving the sampled data; b) derotating a mathematical model of the Lissajous trajectory to account for rotation of the scanned beam imager about the third axis of rotation from a reference orientation; c) constructing the pixel image in the display coordinate system from the derotated model; and d) displaying the constructed pixel image.
