FIELD: instrument making. ^ SUBSTANCE: invention relates to optical hardware designed to measure angular coordinates of distant objects. The proposed invention differs from known designs in that it additionally incorporates a beam splitter, lens ring arranged on the way of the beam reflected from the said additional beam splitter, control unit, three drives of diaphragms, and three diaphragms, each furnished with an orifice. The orifice size and position in the plane of constriction can be varied to transmit only optical radiation from the distant object under analysis. ^ EFFECT: higher validity of measurements. ^ 1 dwg |
