Abstract:
1. A single-channel optical processing system for an energetic-beam instrument; the system comprising: a first optical path for processing radiation; a second optical path for illumination radiation; a combiner; the combiner oriented so that a polarizer positioned in the optical path of the combined incident radiation; a beam splitter positioned in the optical path of the combined incident radiation following the polarizer; a quarter-wave plate located in the optical path of the combined incident radiation, following the beam splitter; a self-focusing rod lens, the rod lens having first and second ends; the self-focusing rod lens located in the optical path of the combined incident radiation following the quarter-wave plate, the beam splitter further oriented so as to reflect the reflected combined radiation at an angle from the optical path of the reflected combined radiation exiting the self-focusing rod lens.
