<p>A radiation shielded optical system (100). In one example, a radiation shielded optical system includes a labyrinthine housing (120) having an entrance and defining a cavity, a detector (110) positioned within the cavity of the housing, the housing (120) configured to provide substantially 4-pi steradian radiation shielding for the detector. The optical system further includes a rear-stopped optical sub-system (130) having a rear aperture stop (140) positioned proximate the entrance of the housing and configured to direct an optical beam through the rear aperture stop and the entrance into the housing, and a fold mirror (160) positioned within the housing (120) and configured to reflect the optical beam onto the detector (110).</p> |
