Abstract
In certain embodiments, an imaging system includes an enclosure with an objective aperture opening into an interior space of the enclosure, an optical assembly optically coupling the objective aperture to an imaging sensor within the enclosure, a shutter mounted to the objective aperture for selectively blocking and admitting illumination through the objective aperture into the interior space, and an illuminator mounted to illuminate the interior space of the enclosure.
Claims20
An imaging system comprising:
- an enclosure with an objective aperture opening into an interior space of the enclosure;
- an optical assembly optically coupling the objective aperture to an imaging sensor within the enclosure;
- a shutter mounted to the objective aperture for selectively blocking and admitting illumination through the objective aperture into the interior space;
- and
- an illuminator mounted to illuminate the interior space of the enclosure.
