1. An endoscope assembly, comprising:

  • an endoscope comprising a first image sensor, a first light source, and a first polarizing filter, wherein the first polarizing filter is disposed over the first light source; and

    an imaging device comprising a second image sensor, a second light source, a second polarizing filter, wherein the second polarizing filter is disposed over the second image sensor, and a curved link configured to extend from a distal end of the endoscope such that the second image sensor and second light source face the first image sensor and first light source, wherein the first and second polarizing filters are configured to reduce light interference between the first light source and the second image sensor, wherein the second polarizing filter blocks light that is transmitted through the first polarizing filter, and wherein there is no polarizing filter over the first image sensor and no polarizing filter over the second light source.
