METHOD FOR CREATING A PIXEL IMAGE FROM SAMPLED DATA OF A SCANNED BEAM IMAGER
First Claim
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.

Abstract
A method for creating a pixel image in a two-dimensional display coordinate system from sampled data derived from a collector of a scanned beam imager adapted to transmit a beam of radiation which traces a trajectory in a two-dimensional acquisition coordinate system. The trajectory contains datum locations in the acquisition coordinate system associated with the sampled data. The method includes receiving the sampled data. The method also includes adjusting a mathematical model of the trajectory based on a function of at least one of rotation, translation, and desired scaling of the model of the trajectory. The method also includes constructing the pixel image in the display coordinate system from the adjusted model of the trajectory.
