The purpose of the invention is a photoelectric tracking device which utilizes a dissector as the sensitive element. At the photocathode of the dissector a point image of the tracking object is projected and a signal from its output is compared in phase with a reference signal. A circular diaphragm is mounted before the anode of the dissector concentric with the axis of the optical system and dissector, and two pairs of deflection coils in the transfer section of the dissector are connected to a stabilized ac source which provides restrictively to each pair of coils sinusoidal voltages of the same frequency and displaced in phase from one another by 90 degrees.
