Abstract

The invention relates to an arrangement for angular measurements, having a rotating divided circle and optoelectronic scanning systems. It can be applied in all geodetic and precision-measuring instruments for measuring horizontal and vertical angles. It is the aim of the invention to carry out angular measurement with high accuracy, reliability of measurement and a low outlay on measuring means for all classes of accuracy and with the exclusion of errors of division. The object of the invention consists, in the case of coarse and fine measurement ranges, in eliminating the influence of the errors in circular division and reading errors at the same time as the angular measurement, without complete rotations of the divided circle. This object is achieved when at least one absolutely coded division is provided concentrically with the measurement division for the rotating divided circle, the scale divisions of the divided circle form at the one reading point the index for the divisions of the other reading point or vice versa, and the size of the angle between fixed and rotatable scanning systems is determined by reading the coded division and from interpolation measurement, and the measurement division and coded division are read simultaneously by the scanning systems.
