Approach is suggested to the construction of optical sensor system for determination of the trajectory of a butt made without edge grooving with a gap close to zero. The sensor allows eliminating several disadvantages of the luminous section method and can serve as a beneficial addition to it.
Keywords: optical sensor, digital filtering, signal/noise ratio, surface roughness, luminous section, infrared illuminator
