Patent ID: 8092377

Claim:
An endoscope device, comprising: an optical coupler having an input end, a first output end and a second output end, the input end being optically coupled to a light source; an image pickup module comprising a lens module and a first bundle of optical fibers, a first end of the first bundle of the optical fibers being optically coupled to the first output end of the optical coupler, an opposite second end of the first bundle of the optical fibers being configured for emitting the light to illuminate an object; a second bundle of optical fibers having a first end optically coupled to an image side of the lens module and an opposite second end; a photodetector with the second end of the second bundle of the optical fibers and the second output end of optical coupler being optically coupled thereto, the photodetector being configured for converting the light into analog electrical signals; and an image processing module configured for converting the analog electrical signals into image signals associated with the object.
