Abstract:
A method for optical dithering and a dither device comprising a mounting structure, a refractive optic, an optic mounting structure surrounding the optic, and one or more linear drive motors. Four linear coils are preferably employed together with a control system operating in open loop mode. The dither device and method provides double resolution to a detector receiving output therefrom. The invention can operate in a single axis or in two axes.
