ABSTRACT:
A circuit for sensor-controlled telemetry has two linear image sensors each having a number of opto-electronic sensor elements on which are projected sections of corresponding lines of two separately-obtained images from an object whose range is to be determined and has a single-input evaluator post connected to each sensor element through switching transistors, which evaluators are switchable between two logic states dependent upon whether a voltage generated by accumulated charge in a sensor element is above or below a reference potential. The digitalized signals from each evaluator are serially transmitted through respective associated shift registers to a logic circuit which compares the contents of stages of shift registers for each image sensor for determining coincidence of the digital signals. The number of coincidences indicate the relative position correlation of the images on the image sensors and this number of coincidences is serially transmitted to another shift register to a counter for determination of a maximum correlation and subsequent generation of an operational range-indicating or range-finding signal.
