METHOD OF GEODETIC MEASUREMENT OF VOLUMETRIC OBJECTS BY SPECIFIED LUMINOUS MARKS AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1997 - IPC

FIELD: geodetic measurements of objects of complex spatial configuration. SUBSTANCE: not less than three luminous marks are formed on surface of tested object. One of them retains spatial coordinates during time of measurement of concrete fragment of tested surface and coordinates of other (peripheral) luminous marks are measured relative to reference luminous mark. Gear setting luminous marks includes laser radiation beam splitter dividing beam into three and more luminous bundles, proper number of rotary devices of peripheral laser bundles fitted with mechanisms counting angle of turn. There can be manufactured some variants of beam splitter. EFFECT: increased authenticity of measurements. 9 cl, 7 dwg
