Abstract
An optical system for an internal drum readout apparatus is disclosed. The optical system includes a hollow cylindrical segment defining a central axis, a support structure configured and adapted to translate along the central axis, a mirror mounted on the support structure for translational movement therewith and for rotational spinning around the central axis, a light source mounted to the support structure for providing a beam capable of being directed along the central axis which in turn is directed against the medium thereby producing a stimulated light, a detector coaxially aligned with the central axis, the detector being configured and adapted to absorb stimulated light direct toward and reflected off of the angled mirror, and a shroud mounted on the support structure for blocking stimulated light not directed toward the angled mirror, wherein the stimulated light not directed toward the angled mirror would otherwise degrade the medium prematurely.
