Abstract

An apparatus for performing an endoscopic procedure for detecting cancerous tissue includes a detection probe for detecting the cancerous tissue. The detection probe includes a first fiber for emitting an ultraviolet light beam having an orthogonal function applied thereto and a second fiber for receiving emissions from tissues responsive to the ultraviolet light beam emitted for the first fiber. An ultraviolet emission source generates the ultraviolet light beam. Orthogonal function circuitry applies the orthogonal function twist to the ultraviolet light beam. Detection circuitry detects fluorescence and orthogonal function within the emissions from the tissues received over the second fiber.
