ABSTRACT:
A theodolite for target tracking and target measuring with a telescope composed of a mirror objective and a collimator. The real image produced by the mirror objective is projected to infinity by the collimator, so that there is formed an afocal beam of light. This beam of light is delivered by means of a partially permeable mirror surface to a television camera and at least one other image evaluation device (camera). The television camera is arranged at the telescope at an unlaterable position with respect to the telescope tube. The partially permeable mirror surface, branching-off part of the beam of light to the television camera, is arranged between the collimator and a further mirror surface serving for fading-in the image of a crosshair at the beam of light. The invention advantageously serves for constructng a theodolite having a control of the target tracking by the signals emanating from the television camera (TV-tracking).
