摘要: A remote reflective materials sensor for detecting remotely located reflective material. The remote reflective materials sensor includes a transparent window with two window surfaces, an amount of reflective material that is remotely located away from one window surface. An operating parameters sensor located adjacent to the transparent window, a radiation detector located away from the other window surface; and two spaced apart radiation emitters located on either side of the radiation detector, and away from the second window surface. Each radiation emitter is configured to emit radiation along one axis through the transparent window towards the reflective material and towards a common focal point. The radiation detector is located to receive reflected radiation from the reflective material along another axis. The first axis of the radiation emitters is angled towards the other axis of the reflected radiation.
