Abstract
An optical, multi-resolution scanning apparatus for scanning transparent or opaque objects including a high resolution lens, a low resolution lens, a flip mirror switch which alternates between high resolution mode and low resolution mode of scanning, a flip mirror switch which alternates between transmissive mode and reflective mode of scanning whereby high and low resolution scanning of opaque and/or transparent objects may be accomplished through movement of flip mirror switches, without transverse movement of the lens assembly.
Claims4
An optical scanning apparatus for retrieving images representative of objects comprising:
- at least one scanning platform capable of holding an object for scanning;
- an optical sensor;
- a lens assembly comprising at least two lenses;
- at least two optical pathways, each pathway including a plurality of mirrors defining a corresponding optical path from at least one scanning platform to said optical sensor through a corresponding one of said lenses;
- and
