FRISO VAN MANSVELT, HANSRUEDI RITTER and CAN WALTER EICHER INVENTION: THEODOLITE FOR TRACKING AND MEASURING A FLYING OBJECT WITH A TV CAMERA ARRANGED AT A TELESCOPE ABSTRACT OF THE DISCLOSURE A theodolite for target tracking and target measur- ing 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 un- laterable 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 constructing a theodolite having a control of the target tracking by the signals emanating from the television camera (TV-tracking).
