An observation-and-measuring theodolite for moving objects which is of the type having at least one image evaluation device which can be directed at each section of a spherical segment surrounding the theodolite. There is provided servomotor means for rotating a housing about a stationary substantially vertical axis of rotation, with a first reflector surface being mounted in said housing at an inclination of 45 DEG with respect to said axis of rotation. Further, an attachment housing is rotatably mounted at the aforesaid housing, this attachment housing possessing a light entry or passage window, and a second reflector surface is mounted in the attachment housing behind said light passage window. This second reflector surface is arranged at an inclination of 45 DEG with respect to a horizontal axis passing through the center of said first reflector surface, with said first reflector surface being situated opposite said second reflector surface. Servomotor means serve to rotate the attachment housing about the horizontal axis connecting the centers of both reflector surfaces, and there is also provided at least one stationary evaluation device. The system is arranged such that light from each spherical segment section, towards which there is momentarily directed the light passage window in front of the second reflector surface, is reflected in the direction of the horizontal connection axis of the centers of both reflector surfaces and at said first reflector surface this light is reflected in the direction of its vertical axis of rotation and then is delivered to said at least one stationary evaluation device. |
