Abstract
A circuit for sensor-controlled telemetry has two linear image sensors each having a number of sensor elements onto which image sensors portions of corresponding lines of two separately obtained images of an object are projected and a number of evaluators post-connected to the sensor elements each being switchable between two states as a function of the amount of charge optionally generated in the sensor elements, each evaluator having two inputs respectively connected through switching transistors to the outputs of two sensor elements for comparing the charges generated thereby. The two sensor elements connected to each comparator may be adjacent to each other or disposed at a small distance from each other. Each evaluator provides a digital output to a shift register for serially transferring the data to a processing circuit which undertakes a maximum correlation of the data received from the evaluators, and transmits the data to a post-connected display or focusing device.
