FIELD: sight monitoring facilities intended for teleorientation in optical beam of vehicles, in particular aircraft using injection lasers as radiation sources. SUBSTANCE: device has radiating channels employing injection filters including an objective and a stop installed in its focal plane, photodetector and an electronic unit for measurement of signal parameters, it has a stop in the form of a reticule of two vertical and one horizontal slits, whose center is positioned in the objective optical axis, a beam splitter is installed behind the stop, light source and photodetector are installed in optically matched axes of the beam splitter, and light filters are installed before the objective in holes made in an opaque partition in such a manner that the rib of the wedge formed by working surfaces of each light filter is perpendicular to the radiation body of the respective laser; the light filters are positioned with respective arrangement of exit pupils of the sight radiating channels; transmission factor of light filters is selected proceeding from equalization of signals produced in photodetector by different sight channels. EFFECT: enhanced accuracy of measurement of misalignment of sight optical axis and sighting line, enhanced adaptability to manufacture and operating characteristics. 1 dwg
