FIELD: measuring technique. ^ SUBSTANCE: pickup comprises multi-mode fiber light guide connected with the part whose angle of rotation should be measured, source of coherent radiation, device for input of radiation to the light guide, and TV camera that records the distribution of intensity of output radiation. The fiber light guide is bent in a plane perpendicular to the plane of rotation. A section of light guide between the radiation source and the initial point the bend is rectilinear. The axis of the rectilinear section of the fiber light guide is positioned at a minimum distance from the axis of rotation of the part. ^ EFFECT: prolonged service life and enhanced reliability. ^ 5 dwg |
