Abstract:
1. An endoscopic device for measuring infrared radiation in a vessel, the endoscopic device comprising: an infrared sensor array; and a fiber-optic channel assembly for communicating infrared radiation to the infrared sensor array, the fiber-optic channel assembly including, a distal end having an end face for collecting infrared radiation along an end view, and a plurality of lenses disposed on a periphery of the fiber-optic channel assembly for collecting infrared radiation along a side view, where the plurality of lenses are longitudinally staggered along a length of the fiber-optic channel and circumferentially staggered around the periphery forming a helical path to collect infrared radiation over a two dimensional area forming the side view, and where the plurality of lenses have sufficiently wide-angle views so as to collectively provide a 360-degree view of circumferential coverage.
