ABSTRACT:
A photographic or electronic camera optoelectronic distance measuring system has a lens with two partial aperture diaphragms which create first and second partial bundles of rays. Two linear image sensors are provided together with optical devices for projecting segments of lines corresponding to two images obtained from the object onto the image sensors. An evaluating circuit, in dependence upon varying position displacements of sensor signals obtained from the one image sensor with respect to the sensor signals obtained from the other image sensor, determines a maximum correlation between these and an associated position displacement. A device is provided for deflecting the ray path at least partially into a view finder. Two focusing lens parts are arranged in a region of an eyepiece of the view finder which locate partial aperture diaphragms of the lens by imaging in the plane of the view finder eyepiece. In a path of rays of partial bundles of rays created by the partial aperture diaphragms, and which project images onto the image sensors, deflection elements are provided which separate both paths of rays from one another.
