Patent ID: 8556806

Claim:
A device for insertion into a body cavity, the device comprising: a tubular portion having a proximal end and a distal end, the distal end being configured to be at least partially inserted into the body cavity; an objective lens assembly positioned in the rigid section of the tubular portion; an image capture device positioned to capture imaging rays through the objective lens assembly in the rigid section of the tubular portion; an optical assembly configured to collect spectral imaging data from an area inside the body, wherein the optical assembly is configured to incorporate at least two separate wavelength dependent images with separate light spectra; one or more light sources configured to illuminate the area inside the body and positioned on an internal sidewall of the rigid section such that light from the one or more light sources is directed radially inward; a beam splitter configured to combine the illumination from first and second light emitting devices of the one or more light sources into a path of imaging rays; and optics comprising first and second dichroic beam splitters, the first dichroic beam splitter configured to transmit a first red/green/blue set from the first light emitting devices and to reflect a second, complementary red/green/blue set from the second light emitting devices through a first stereo port, and the second dichroic beam splitter configured to transmit the second, complementary red/green/blue set from the second light emitting devices and to reflect the first red/green/blue set through a second stereo port separate from the first stereo port.
