Polarizing endoscopy system and method

A medical device comprising:

• a housing having a first channel and a second channel;
• a light source coupled to the first channel;
• an optical system housed within the second channel, said optical system comprising a plurality of otoscopy lenses;
• a first polarizing filter positioned within the first channel, wherein the first polarizing filter is configured to polarize light from the light source;
• and
• a second polarizing filter positioned within the second channel for receiving reflected light from the light source, the reflected light received through a sensor axially aligned with the second channel, wherein a distal end of the first channel and a distal end of the second channel comprise a common radial plane;
• wherein the second polarizing filter is rotatably adjustable relative to the first polarizing filter.

A method of polarizing light for medical examination comprising:

• producing light from a light source within a first channel of a medical device;
• polarizing the light produced from the light source by a first polarizing filter;
• transmitting the polarized light from the first channel to a first radial plane;
• reflecting the light off a target;
• receiving the reflected light into a second channel of the medical device at the first radial plane;
• polarizing the reflected light by a rotatably adjustable second polarizing filter;
• and
• receiving the polarizing reflected light by a lens.
