The invention relates to a time measurement circuit and an optoelectronic range finder using such a time measurement circuit. The time measurement circuit and for an incoming signal, in such a condition, has a comparator stage for generating a comparator output signal depending on a fulfillment of a criterion by the incoming signal, wherein exceeding or falling below a threshold value is defined as the criterion. Furthermore, a digitization stage is provided, for sampling, which is performed at a defined sampling rate, of an input signal fed to the digitization stage and converting it into digital data containing sampled values for the input signal, and an evaluation unit for determining a chronological location for the incoming signal by evaluating the digital data. A signal generating stage is interconnected between the comparator stage and the digitization stage, which is designed to generate and output, in a chronologically fixed manner dependent on the content of the comparator output signal, a shape signal, which is designed for post-sampling interpolation ability, of known shape. The evaluation unit then determines the time for the incoming analog signal while using a chronological interpolation of the values contained in the digital data and the known shape of the shape signal.
