Abstract (en)
[origin: US5255066A] The measuring device for track building machines comprises an optical receiver device having two lenses (1, 2) aligned in one axis (3) and in each case at least one associated sensor strip (4, 5). The projections of light sources (A, B, C) disposed outside the receiver device onto the sensor strips (4, 5) produce signals which are evaluated and determine the size of the angle of the light source in relation to the optical axis. The provision of light-sensitive sensor strips (4, 5) makes it possible to dispense in an advantageous manner with mechanically rotating components in the receiver device.
